AB  - This study presents the results of an investigation of high-temperature materials refractory coatings based on different refractory fillers including talc, cordierite, zircon and mullite applied in the lost-foam casting process. Design and optimization of a coating composition with controlled rheological properties and synthesis were achieved by applying different coating components, suspension agents and fillers and by altering the coating-production procedure. A morphological and microstructural analysis of the fillers was carried out with scanning electron microscopy. An X-ray diffraction analysis was applied to determine and monitor the phase-composition changes of the refractory fillers. The particle size and shape were assessed with the PC software application package OZARIA 2.5. To assess the effects of the applications of individual refractory coatings, a detailed investigation of the structural and mechanical properties of the mouldings obtained was performed. Highlight was placed on revealing and analyzing surface and volume defects present on the mouldings. Radiographic moulding tests were carried out with an X-ray device, SAIFORT type-S200. The attained results are essential for the synthesis of the refractory coatings based on high-temperature fillers and their applications in the lost-foam casting process for manufacturing the mouldings with in-advance-set properties.

AB  - The efficiency of talc mechanical activation by means of two different mechano-activators centrifugal and attrition mill is investigated in this study and the comparative analysis of the characteristics of obtained talc powders is presented. A new approach for obtaining high-grade talc concentrate with low Fe2O3 content is achieved through effect of mechanical activation of talc accompanied by hydrometallurgical process. The applied mechanical activation process conditions of ultra-centrifugal mill were defined by number of rotor revolutions, sieve mesh size, and current intensity. These operating parameters of the ultra-centrifugal mill were variable. Ultra fine grinding of talc in attrition mill (attritor) was carried out in various time intervals - from 5 to 15 min. The following technological parameters of the mechanical activation were monitored: time of mechanical activation, circumferential rotor speed, capacity of ultra-centrifugal mill, and specific energy consumption. The investigation was based on a kinetic model. The structure and behavior of activated samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, and differential thermal analysis (DTA).

AB  - Mica and talc have wide areas of application as a raw material in a number of industrial branches. Mechanically activated mica has specific applications such as: capacitors, insulators, and pearlescent pigments. Talc is widely used as either a basic raw material or as filler. This paper presents a comparative analysis of mechanically activated samples of mica and talc in ultra-centrifugal mechano-activator "Retsch ZM-1". The following mechano-activator parameters were variable: number of rotor revolutions (rpm); sieve mesh size (mu m); current intensity (A). In addition, the following parameters were monitored: duration of mechanical activation, t (min); circumferential rotor speed, v (m/s); capacity of mechano-activator, Q (kg/h); and specific energy consumption, W-e (kW h/t). It was observed that effect of mechanical activation of mica and talc increased with an increase of the load and rotor revolution of ultra-centrifugal mechano-activator. Both mica and talc were successfully treated by mechanical activation procedure. In the processing of mica, mechanical activation is suggested to be applied as a post-treatment, and in the talc processing as a pre-treatment, as the high quality talc is obtained by means of hydrometallurgical concentration method.

AB  - In this study, new refractory coatings based on synthesized cordierite for the casting applications were developed. The investigation included starting raw materials characterization, synthesis of the cordierite, design of the refractory coating as final product, and its application testing. The obtained results pointed out that coating suspension sediment stability was crucial quality parameter. Design and optimization of the coatings composition, with controlled rheological properties included, were achieved by application of different coating components, namely different suspension agents and by alteration of the coating production procedure. Cordierite, used as filler, was obtained by means of synthesis in the solid-state reaction on the basis of talc, kaolin, and alumina. The investigation showed that the application of these particular types of water/alcohol-based coatings has positive influence on surface quality and structural and mechanical properties of the castings of aluminum alloys obtained by casting into sand molds by means of evaporable models method, that is, evaporate pattern casting process.

AB  - This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes. The micronized powder was investigated by means of differential thermal and thermogravimetric analyses, analysis of the degree of micronization, the specific surface area analysis, and X-ray diffraction analysis. The achieved results pointed out that dry mica micronization grinding which exceeds 360 minutes is recommended for this type of mill. However, it was also shown that the micronized mica produced by means of planetary ball mill after extra long periods of micronization grinding can pass into amorphous state.

AB  - This work investigated the possibility of developing new chromite-based refractory coatings for hot metal casting applications. The coating composition and rheological properties were optimized by careful choice of binding agents and addition of a suspension maintenance agent in the coating. Different solvents (water and isopropyl alcohol) and casting methods were used in the tests. Chromite was used as refractory filler in both the water- And alcohol-based coating compositions. The chromite was examined by X-ray diffraction analysis and scanning electron microscopy. The chromite shape and grain size were analysed visually with the aid of the OZARIA 2.5 PC image analysis package. Test samples were cast using sand moulds and by the method of expandable patterns using a polymer model, also known as the "lost foam" casting process. The investigation demonstrated that water- And alcohol-based coatings have positive influence on the surface quality, structural and mechanical properties of alloy castings made with both casting processes.

AB  - Various possibilities for developing new mullite-based refractory linings that can be applied in a casting process were investigated and are presented in this paper. An optimization of the refractory-lining composition design with the controlled rheological properties was achieved by applying different lining components and altering the lining-production procedure. Mullite was used as a high-temperature filler. A mullite sample was tested with the following methods: X-ray diffraction analysis, differential thermal analysis and scanning-electron microscopy. The particle shape and particle size were analyzed with the program package for an image analysis called OZARIA 2.5. It was proved that an application of this type of lining has a positive effect on the surface quality, structural and mechanical properties of the castings of Fe-C alloys obtained by casting into sand molds, according to the method of expandable patterns (the EPC casting process).

AB  - The aim of this study was to investigate the influence of various process parameters on the microstructure of composite materials based on alloys All 8Wt%Si with the addition of 10Wt%SiC. The effect of stirring speed (1000 and 1500 rpm), stirring time 15 min and casting temperature 565 degrees C on the structural and mechanical properties are discussed. It was found that applying the stirring speed of 1500 rpm in semisolid state the best distribution of SiC particles in the matrix was achieved, which gave satisfying mechanical properties. In order to evaluate the quality of obtained composites and their possible application in the practice, tests were carried out under conditions of cavitation. Cavitation damage to the composite samples was determined using modified vibratory cavitation equipment. Mass loss and surface analysis of composite samples during the experiment were used as an indicator the level of cavitation damage. The results showed very good cavitation resistance which gives the possibility of using these materials in condition where cavitation resistance is needed.

AB  - Hypereutectic Al-18wt%Si alloy was obtained by conventional and rheocasting procedure at cooling rate 0.16 +/- 0.05 degrees Cs-1. Samples of rheocasted alloy were obtained at two stirring speeds 1000 and 1500 rpm. Tests showed that two major changes of microstructural properties of rheocasting alloy, in comparison with conventional alloy, are change of dendrite morphology into nondendrite one and change of primary phases size (alpha-Al and Si). Both changes of primary particles were monitored in area near the stirrer and at a small distance from the crucible wall. Test showed that sizes of primary, alpha-Al particles decreased with stirring speed increment, while roundness of particles increased with stirring speed increment. Stirring speed change led to different degree of primary Si particles agglomeration. At stirring speed 1000 rpm, Si particles are uniformly distributed, while at speed 1500 rpm, a tendency to form clusters is more expressed. Test results were discussed on basis of utilizing fragmentation-agglomeration mechanism of primary phase evolution in a semi-solid melt, which may contribute to explanation of semi-solid structure development.

AB  - Leteći pepeo koji je deponovan na otvorenom predstavlja veliki rizik za prirodno okruženje. Održivo rešenje za sprečavanje zagađenja jeste primena letećeg pepela u građevinskim materijalima. Građevinski kompoziti - visokotemperaturna veziva, u kojima je leteći pepeo kombinovan s vatrostalnim komponentama, jesu nova mogućnost za reaplikaciju ovog otpadnog materijala. U ovom istraživanju, ispitivano vezivo dobijeno je na bazi letećeg pepela u kombinaciji s visokoaluminatnim cementom. Leteći pepeo je prethodno bio podvrgnut mehaničkoj aktivaciji. Analiza mineralnih faza pomoću XRD metode naglašena je zbog promena koje u materijalu nastaju s povećanjem temperature. Procesi koji se dešavaju u kompozitu u toku termičkog tretmana od 20 do 1100 oC identifikovani su DTA metodom. Analizirano je luženje i potencijalni uticaj na prirodnu sredinu. Ispitivani kompozit na bazi pepela i cementa pokazao je visoke fizičko-mehaničke performanse i dobra termoizolaciona svojstva. Sveukupni rezultati pokazali su da primena letećeg pepela za dobijanje visokotemperaturnih veziva predstavlja održivo rešenje za problem odlaganja i reciklaže ovog opasnog otpadnog materijala.
AB  - The fly ash disposal on open landfills poses significant risk to the environment. Sustainable solution for the pollution-prevention is reuse of fly ash in building materials. Building composites - high temperature bonding agents, in which fly ash is combined with refractory components is new option for reapplication of this waste material. In this study, investigated bonding agent was based on fly ash mixed with high-aluminate cement. Fly ash previously underwent mechanical activation. Mineral phase analysis of the composite by means of XRD was accented due to the changes occurring with increasing temperature. Processes taking place during composite thermal treatment from 20 up to 1100 oC were identified by means of DTA method.

The leaching behaviour and potential environmental impact of 11 potentially hazardous elements was tracked: Pb, Cd, Zn, Cu, Ni, Cr, Hg, As, Ba, Sb and Se. A detailed study of physico-chemical characteristics of the fly ash, with an accent on trace elements and the chemical composition investigation is included. Physicochemical properties of fly ash were investigated by means of X-ray fluorescence, differential thermal analysis and X-ray diffraction methods. Scanning electron microscopy was used in microstructure analysis. The results show that most of the elements are more easily leachable from the fly ash in comparison to the fly ash based composites. The leaching of investigated pollutants is within allowed range thus investigated fly ashes can be reused in construction materials production.

Optimization of coating composition with controlled rheological properties was attained by applying different coating components, and by alteration of coating production procedure. As filler, corundum powder with particle size of 20x10(-6) m and 40x10(-6) m was used. The corundum sample was tested by the following methods: X-ray diffraction analysis and with polarized microscope. The shape and grain size were analyzed by the program package OZARIA 2.5. It was shown that application of this type of water-alcohol-based coating had a positive influence on surface quality, structural and mechanical properties of the castings of Fe-C and Al alloys obtained by casting into sand molds, according to the method of expandable patterns (EPC process).

AB  - In this study the testing results of the possibility of substituting mill lining plates for ore milling made of low chromium white iron that is resistant to wear with plates made of basalt melt are presented. Plates made of chromium white iron with 10% Cr and plates made of basalt from the ore of Kopaonik - Serbia are both produced by the sand mould casting method. The microstructure characteristics and properties of metal and basalt plates have been tested depending on the parameters of the melting and casting process, the cooling regime and the crystallization of castings. Testing of the application of basalt plates in exploitation in industrial conditions has proved to have good results.

AB  - In this work, a possibility to develop new chromite-based refractory linings for casting applications has been examined. Lining composition optimization with the controlled reologic properties was achieved by applying different lining components and by alteration of lining production procedure. As filler, chromite was used. The chromite sample was tested by the following methods: X-ray diffraction analysis, diffraction thermal analysis and SEM. The shape and grain size were analyzed by the program package OZARIA 2.5. It was shown that application of this type of water-alcohol-based lining had a positive influence on surface quality, structural and mechanical properties of the castings of Fe-C alloys obtained by casting into sand molds, according to the method of expandable patterns (Lost foam casting process).

AB  - Cordierite ceramics have an important role in modem technology. Standard raw materials, kaolinite, tale, magnesia, alumina were used in synthesis of cordierite ceramics. Composition of cordierite ceramics is 2MgO-2Al 2O 3-5SiO 2. Synthesized cordierite was used as a refractory filler in the ceramic layer for evaporative polystyrene patterns in the new casting technology, Lost Foam Process. Cordierite characterization was carried out by X-ray structure analysis. Powder particles morphology was analysed by the scanning electronic microscope. The characteristic temperatures for carrying out solid state reactions in the three-component system of MgO-Al 2O 3-SiO 2 were determined differentially by thermal analysis in the range from ambient temperature to 1100°C. Obtained ceramic coatings were applied to polystyrene pattern of 20 kg/m 3 density, polystyrene grain size of 1.5 mm, followed by "full mould" casting. For the purpose of realistic evaluation of possible cordierite application in the production of evaporative pattern ceramic coatings, concurrent analyses with talc based lining were carried out. Cordierite has wide application in electrothermics, electronics and engineering industry, however, it has not been used in casting yet.
