Abstract: This study investigates the mineralogical and chemical composition of shale raw material obtained from the Jerdanak deposit in the Sherabad district of Uzbekistan for its potential use in refractory brick production. The shale samples were crushed, sieved, and thermally treated to evaluate their physical and structural transformations. Analytical techniques such as FTIR spectroscopy and X-ray fluorescence (XRF) were applied to determine the presence of silicate, alumina, and oxide phases. The main components identified include SiO₂ (49.16%), Al₂O₃ (32.36%), and K₂O (11.96%), which correspond to quartz, feldspar, and mica/illite minerals. Minor elements such as Fe, Ti, Mn, and Ca were also detected. The results indicate that the Jerdanak shale possesses a composition suitable for use as an additive in aluminosilicate-based refractory materials, potentially enhancing their thermal stability and mechanical performance.
