AB  - Raw clay samples from Serbia, mainly of kaolinitic, illitic and mixed nature, were
tested for their possible application in the production of ceramics. Using various triaxial
diagrams, the samples were sorted according to their chemical and bulk mineralogical
makeup, and also particle size distribution to determine whether they could be
employed in the production of ceramics and refractories. The areas in the ternary graphs
determined in earlier studies concerning the expected color after firing and the
applicability of the raw clays are checked and extended. The samples' water absorption
and flexural strength were assessed using EN standard procedures after they had been
hydraulically semi-dry pressed and fired at several peak temperatures between 1100
and 1300 °C. A novel triaxial diagram considering the position of the samples based on
firing temperature, water absorption and modulus of rupture is proposed, and the areas
of different kinds of ceramic tiles are defined. It is discovered that the different raw
clays can be utilized to create refractory, as well as wall and floor tiles. This study
supports the rational use of natural sources of raw materials.

AB  - The chemical compositions of refractory materials, such as high-alumina concrete, bricks, and putty, were analyzed using an energy-dispersive X-ray spectrometer (EDXRF). An improved methodology for investigating the effect of particle size on the outcomes of EDXRF chemical analysis is presented. Eight independent refractory samples (refractory concrete, brick, and putty) were pulverized utilizing seven milling times (30, 60, 120, 180, 240, 300, and 360 s) and compared to non-pulverized samples. Thus, sixty-four refractory samples were obtained and analyzed using EDXRF. The method for measuring the fundamental EDXRF characteristics was then tested with ten certified reference materials. The acquired data were compared using inductively coupled plasma atomic emission spectrometry (ICP-OES). Univariate and multivariate statistics are used to evaluate EDXRF data. The particle size of the tested samples affected the z-scores of SiO2, Al2O3, Fe2O3, TiO2, CaO, MgO, Na2O, K2O, and P2O5 concentration measurements. Grinding times for refractory concrete, brick, and putty samples were determined in order to validate the robustness of the EDXRF technique and provide reliable chemical analyses. The ideal milling times for the samples studied ranged from 180 to 360 s, depending on the type of refractory material.

AB  - In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such as loose powder, pressed pellet, and fired pressed pellet. The fired pressed pellet approach was observed as a part of universal sample preparation for physic, mechanical, and instrumental analysis, which has not been previously tested as a solution in chemical analysis by the EDXRF method. The observed sample preparation techniques were compared by calculating the parameters of validation (recoveries, limit of detection-LOD, limit of quantification - LOQ, precision, and expanded uncertainties of measurements) of 11 elements (Si, Al, Fe, Ca, Mg, K, Na, Ti, P, Mn, and S) using 15 certified reference materials (CRMs). Calibration curves were created and evaluated using 30 reference materials (RM) for all three approaches. Results proved that the fired pressed pellet is the most practical and precise approach for sample preparation of raw clays.

AB  - Surface sediments collected from twelve stations in the Boka Kotorska Bay were analyzed for the level and distribution of twenty-six elements and ten oxides, grain sizes, organic matter, and carbonate content. Potentially toxic elements (Al, Fe, Mn, Cr, Zn, Ni, Cu, Pb, As, Co, U) were determined to assess the contamination status and potential environmental risk according to the single-element indices (enrichment factor (EF), geoaccumulation index (Igeo), contamination factor (CF)), and combined index (pollution load index (PLI)). The single-element indices EF and CF revealed that the surface marine sediment was moderately polluted with Pb, Cu, and Cr, while Igeo indicated moderate pollution with Ni > Cr > Zn > Cu > As and moderate to heavy pollution with Pb, as a result of the anthropogenic factors. The method of the combined effect of toxic elements, PLI, showed the highest pollution rate at the shipyard location in the Bay of Tivat. Pearson's correlation coefficient (r), principal component analysis (PCA), and cluster analysis (CA) were applied to highlight similarities and differences in the distribution of the investigated elements in the Bay, confirming the claim obtained by the pollution indices. The sediment contamination with most heavy metals, such as Cr, Zn, Ni, Cu, Pb, and As, has been identified in the Tivat Bay area.
