Claim Text:
1. A method of producing inorganic compound particles of a composite including Mg and Si, the method comprising the steps of: impregnating a melt liquid of second raw particles into first raw particles by heating a raw material including the first raw particles, at least some of which contain Si as a major constituent element, and the second raw particles, which contain Mg as a major constituent element, 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 of Mg and Si, and lower than the melting temperature of the inorganic compound; and synthesizing the inorganic compound particles by a reaction in the first raw particles between the element contained in the first raw particles and the element contained in the second raw particles wherein heating in the step of impregnating is performed at a temperature of 650° C. or higher and lower than 945.6 ° C, particle sizes of the first raw particles are more than 20 μm and equal to or less than 500 μm, and particle sizes of the inorganic compound particles are more than 25 μm and equal to 1 mm or less after the step of synthesizing the inorganic compound particles.
