info@rsrefractories.comSilicon Carbide Bricks are advanced refractory materials produced from high-purity silicon carbide combined with binders through high-temperature sintering or reaction bonding technology. These bricks demonstrate outstanding properties including high thermal conductivity, low thermal expansion, excellent thermal shock resistance, and superior strength at elevated temperatures. Their strong resistance to alkalis, acids, and slag erosion makes them ideal for harsh industrial environments. Due to their exceptional durability and energy-saving performance, SiC bricks are widely used in furnaces requiring fast heat transfer, wear resistance, and chemical stability.
