This article investigates the resistance of bricks made from secondary kaolin obtained from the Angren region
to liquid metal. Secondary kaolin is a by-product of industrial processing, and its physicochemical properties are suitable
for refractory materials. During the study, the thermal stability, mechanical strength, and corrosion resistance of the bricks
were evaluated. Under laboratory conditions, the density, porosity, and structure of the bricks were analyzed. The results
showed that the bricks made from Angren secondary kaolin exhibit high resistance to elevated temperatures and liquid
metal, making them suitable for use in metallurgy and high-temperature industrial processes. This research provides a
scientific basis for the efficient utilization of local raw materials and the optimization of refractory brick production.
