The refractory Sintered Silicon Carbide Ceramic (RBSIC or SiSiC) Sealing Parts can keep high strength and super corrosion resistance under high temperature (approximately 1600℃). It has better thermal shock resistance, heat conductivity, and abrasion resistance, and the hardness closes to the diamond. So Atmospheric pressure sintered silicon carbide is the ideal material for production of seal ring for chemical pumps, bushes, high temperature burner nozzles, ultra - high temperature and/or ultra - thin kiln furniture, etc.
