Abstract
A ceramic composite material comprises a ceramic material constituting a matrix, and dispersion particles disposed in the matrix in a dispersing manner. A specific shape of a ceramic composite material is, for instance, a sinter or a thermally sprayed layer. The dispersion particles are consisting of a composite oxide including at least one kind of a first metallic element selected from alkaline earth metals such as Mg and Ca, and at least one kind of a second metallic element selected from W, Ti, Ta, Mo, Nb, V, B, Te, Ge and Si, for instance, are composite oxide particles precipitated by reacting a compound containing a first metallic element and a compound including a second metallic element through heat treatment. The precipitated particles consisting of such a composite oxide can be dispersed as planar particles or acicular particles in the ceramic layer to which, for instance, thermal spraying is applied. The dispersion particles suppress deterioration of strength or toughness of the oxide based ceramic material under high temperature atmosphere.
