Abstract

PURPOSE:To increase the density of the titled sintered body and to improve the characteristics at high temp. by incorporating prescribed percentages of cubic zirconium oxide, yttrium silicate and beta-form silicon nitride. CONSTITUTION:This silicon nitride sintered body is composed of, by volume, 3-25% cubic zirconium oxide, 0.1-10% yttrium silicate and >=50% beta-form silicon nitride. Since the cubic zirconium oxide grains dispersed in the sintered body inhibit the grain boundary slip of the Si3N4 grain boundaries at high temp., the characteristics of the Si3N4 sintered body at high temp. are improved.
