Abstract
PURPOSE:To produce the title sintered body having excellent strength by sintering a system consisting of the whiskers of SiC or Si3N4 and Si powder in a specified pressurized N2 atmosphere at a temp. lower than the m.p. of Si. CONSTITUTION:The whiskers consisting essentially of at least one kind between SiC and Si3N4 and Si powder are mixed, the mixture is compacted, and the compact is sintered at a temp. lower than the m.p. of Si and at 1.5-10atm. N2 partial pressure. Consequently, the whiskers are bound by the Si3N4 formed by the reaction of Si with N2, and a sintered body is obtained. Meanwhile, the sintered body can be further sintered in an N2 atmosphere at 1,600-2,100 deg.C. By this method, the formation of an Si melt is prevented at the time of nitriding Si, the reaction of the whiskers with Si is inhibited, and the deterioration of the whiskers and the generation of voids due to the reaction are controlled. Accordingly, the inherent strength of the whisker is exhibited, and a sintered body having excellent bending strength and toughness can be obtained in the succeeding sintering.
