Sintered Silicon Carbide Seal (SSiC) represents an advanced ceramic product renowned for its exceptional properties, including high hardness and strength on par with diamond. This lightweight material exhibits remarkable characteristics such as strong wear and corrosion resistance, elevated-temperature resilience, and high thermal conductivity. The manufacturing process involves processing fine particles of α-SiC and additives to create granulation powder, which is subsequently pressed into blanks. The key step lies in carefully controlling the sintering temperature, where, within a vacuum sintering furnace at 2100℃, the α-SiC crystals undergo controlled growth. This meticulous process results in the formation of a high-purity and high-density silicon carbide material, ensuring the SSiC's superior performance across various demanding applications.
