Abstract
PURPOSE:To improve the strength and toughness of the titled sintered body by coating the surface of zirconia powder with a reaction preventing layer so as to prevent the direct contact of the zirconia with silicon nitride and to inhibit the formation of zirconium nitride. CONSTITUTION:The particle surface of silicon nitride powder is coated with a sintering assistant layer so as to promote sintering. The particle surface of zirconia powder to be dispersed in a silicon nitride matrix is coated with a reaction preventing layer so as to prevent the reaction of the zirconia with silicon nitride and to also prevent the diffusion of the sintering assistant into the zirconia. The silicon nitride powder coated with the sintering assistant layer is mixed with the zirconia powder coated with the reaction preventing layer and the mixture is molded into a desired shape and sintered.
