Silicon nitride products for blast furnace and aluminum electrolytic cell

Silicon nitride combined with silicon carbide products refers to the use of SiC and Si as raw materials, in the nitriding kiln at 1300~1450 ℃ under the nitrogen atmosphere of heating and the refractory products. It has good alkali corrosion resistance, resistance to molten cryolite wetting, oxidation resistance, wear resistance, high thermal conductivity and thermal shock resistance and very low electrical conductivity.
