I produced a sheet of clay bonded silicon carbide, silicon carbide as the product to raw materials, combined with high quality clay for high temperature, high temperature firing of a high quality silicon carbide products. Good thermal conductivity of the product, oxidation ability, low-temperature furnace used in good effect, is a high-quality mid-range silicon carbide products. Suitable for various industrial furnaces, as wall panels used in high-temperature furnace is also used as a lining material.
