INORGANIC-COMPOUND PARTICLES AND PROCESS FOR PRODUCING SAME

摘要

A method of producing inorganic compound particles is provided. It includes a step of impregnating a melt liquid of second raw particles into first raw particles by heating a raw material including them at a temperature, which equals to or higher than an eutectic temperature between a region-II (solid-liquid phase range) and a region-I (solid phase range) in a phase diagram and lower than the melting temperature of the inorganic compound. The first raw particles contain an element with a melting point equals to or higher than a melting point of the inorganic compound. The second raw particles contain an element with a melting point lower than the melting point of the inorganic compound. The method also includes a step of synthesizing inorganic compound particles by a synthetic reaction in the first raw particles between the elements contained in the first and second raw particles
