Ceramic composite particle and production method thereof

摘要

A ceramic composite particle having an average particle size of 0.1-120 mu m, which comprises uniformly dispersed fine ceramic particle phases and a binder phase. The fine ceramic particle phases, each having a particle size of 1 nm to 1 mu m and comprising a ceramic primary particle, are bound together through the binder phase which is formed by a reaction between a sintering aid and a ceramic particle. The ceramic composite particle may be produced by heat-treating a homogeneous mixture of the ceramic particle and the sintering aid until the binder phase appears. The ceramic composite particle has a good moldability and provides a highly densified sintered body with a high strength.
