Silicon carbide refractory materials are refractory products using silicon carbide as raw material and main crystal phase. Because the raw material and main crystal phase of silicon carbide refractory products is 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 into a whole by a binder. Therefore, the properties and bonding form of the binder have a consider. able impact on the properties of the product.
