PRODUCTION OF COMBINED SINTERED COMPACT

摘要

PURPOSE:To produce a high hardness combined sintered compact. CONSTITUTION:A mixture of alpha-silicon nitride powder with yttria powder, aluminum nitride powder and silicon carbide powder having 0.8-5wt.% oxygen content is sintered to produce the objective combined sintered compact contg. alpha-sialon, beta-sialon and silicon carbide as principal components.
