A kind of Silicon carbide ceramic, containing carborundum crystals, 4H type carborundum crystals containing 0.1～25 mass % and the 6H type carborundum crystals of 50～99.9 mass % in carborundum crystals, preferably the content of nitrogen is below 0.01 mass %, the multiple carborundum particles more preferably containing silicon carbide-containing crystal and the silicon making carborundum particle be combined with each other, the containing ratio of silicon is 10～40 mass %.The Silicon carbide ceramic that the variable quantity of the resistivity that offer variations in temperature causes is little, can be generated heat by energising. |
