Silicon carbide powder and method for producing same
A high-purity silicon carbide powder and its production method enable mass production of the high-purity silicon carbide powder at low cost in a safe manner. The content of impurities in the silicon carbide powder is 500 ppm or less. The silicon carbide powder can be obtained by heating a raw material for silicon carbide production in an Acheson furnace using a heat generator. The raw material for silicon carbide production is prepared by mixing a siliceous raw material and a carbonaceous raw material. The raw material for silicon carbide production contains the siliceous raw material and the carbonaceous raw material at a mixture mole ratio (C/SiO2) of 2.5 to 4.0 and has a content of impurities of 120 ppm or less.
