Abstract

PURPOSE:To form an aluminum oxide-based sintered body having superior wear resistance and strength by using aluminum oxide as a matrix and silicon carbide composed of silicon carbide whiskers and fine silicon carbide particles in a specified ratio as a dispersed phase. CONSTITUTION:This sintered body consists of 30-40vol.% dispersed phase of silicon carbide and the balance aluminum oxide-based matrix with inevitable impurities. The dispersed phase is composed of 50-75vol.% silicon carbide whiskers and the balance silicon carbide particles of <=1mum average particles size. In the sintered body, the pref. average particle size of the aluminum oxide is <=1mum, the pref. average diameter of the silicon carbide whiskers is 0.3-1.0mum and the pref. aspect ratio is 20-60.
