Abstract:
A method of producing a ceramic composite particle, said ceramic composite particle having an average particle size of 0.1-120 .mu.m, which comprises a plurality of fine ceramic particle phases and a binder phase formed by a reaction between a fine particle of at least one ceramic material and a sintering aid, each of said fine ceramic particle phases comprising a fine primary particle of said at least one ceramic material and having a particle size in the range of 1 nm to 1 .mu.m and said fine ceramic particle phases being bound together through said binder phase, the method comprising the steps of:preparing a homogeneous powder mixture of said fine particle of at least one ceramic material and said sintering aid; andheat-treating said homogeneous powder mixture at 1200-1500.degree. C. until said binder phase is formed by a reaction between said sintering aid and said fine particle of at least one ceramic material.
