SILICON CARBIDE SINTERED BODY

摘要

PURPOSE:To enhance the density, strength and thermal shock resistance of a silicon carbide sintered body by specifying the sintered body and coating the pores in the sintered body with a silicon carbide coating film formed by a vapor phase method. CONSTITUTION:This silicon carbide sintered body is produced by coating the pores in a specified sintered body with a silicon carbide coating film formed by a vapor phase method. The coating film contains >=60% beta=SiC. The specified sintered body is obtd. by sintering silicon carbide powder contg. >=70wt.% powder of <=10mum average particle size as starting material.
