Abstract
A highly dense Si.sub.3 N.sub.4 sintered body having a substantially crystalline intergranular phase, which has an improved mechanical strength at high temperatures and excellent static fatigue properties so as to be particularly useful for high temperature structural components or parts, is produced by sintering a molded body of a blend comprising Si.sub.3 N.sub.4, Y-, Mg- and Ce-compounds with a specified composition range.
