Silicon carbide refractory materials are refractory products with silicon carbide as raw material and main crystal phase. Because the raw material and main crystal phase of silicon carbide refractory products are mainly silicon carbide, many properties of the products depend on the properties of silicon carbide. In this type of refractory products, silicon carbide is a barren material and must be bonded as a whole by a binder, so the properties of the binder and the bonding form have a considerable influence on the properties of the product.
