Abstract

PURPOSE:To obtain fiber-reinforced ceramics, having a higher strength and toughness than those of a compact prepared by a hot-pressing method without anisotropy in characteristics of the calcined compact, by forming a blend composition consisting of silicon carbide whisker, calcining assistant, such as alumina or sialon, calcining the resultant compact under ordinary pressure and then calcining the obtained compact under a gas pressure. CONSTITUTION:A blend composition containing 5-30wt.% silicon carbide whisker, <=10wt.% AlN, 1-30wt.% Al2O3 and 1-30wt.% one or more of oxides or compound oxides of a metallic element selected from group IIa or IIIa of the periodic table so as to provide 5-40wt.% total amount and the remainder consisting essentially of Si3N4 or sialon is formed by a conventional method. The resultant compact is then calcined in a nonoxidizing atmosphere at 1,600-1,850 deg.C until open pores are lost and then calcined under a gas pressure in a nonoxidizing atmosphere at 1,600-2,000 deg.C under 1.5-100atm.
