Silicon Carbide Bricks (SiC Bricks)

Silicon carbide bricks are primarily made from silicon carbide (SiC) as the main raw material. Since SiC forms covalent bonds, it does not exhibit typical sintering behavior. Instead, sintering is achieved through the formation of new phases via chemical reactions, known as reaction sintering.
