| description | Provided are: a silicon nitride powder slurry for use in mold release material and capable of forming, on a polycrystalline silicon casting mold, a mold release layer which exhibits favorable mold release properties of a polycrystalline silicon ingot, and which exhibits favorable adhesion to the casting mold after casting the polycrystalline silicon ingot, without requiring use of an additive such as a binder, and without requiring execution of a baking step; a method for producing the same; a silicon nitride powder for mold release material; mold release material; a silicon nitride powder for a slurry use for obtaining the silicon nitride powder slurry for use in the mold release material; a method for producing the same; a polycrystalline silicon casting mold which exhibits favorable mold release properties of a polycrystalline silicon ingot; and a low-cost method for producing the same. The present invention pertains to a silicon nitride powder to be used in a slurry for forming a mold release layer of a polycrystalline silicon casting mold, wherein the specific surface area thereof is 5-50m 2 /g, the proportion of amorphous silicon nitride is 1.0-25.0 mass%, and the oxygen content is 0.6-2.5 mass%. |
