摘要

A silicon nitride powder for a release agent of a polycrystalline silicon ingot casting mold, having a specific surface area of 5 to 40 m²/g, wherein, assuming that a content ratio of oxygen present in a particle surface layer is FSO (mass %), a content ratio of oxygen present inside a particle is FIO (mass %), and the specific surface area is FS (m²/g), FS/FSO is 8 to 30 and FS/FIO is 22 or more, and a ratio D10/D90 between a 10 vol % diameter D10 and a 90 vol % diameter D90 in a measurement of a particle size distribution on a volume basis by a laser diffraction particle size distribution meter of 0.05 to 0.20.
