Self-bonded silicon carbide refractory components have advantages such as good high-temperature resistance, chemical corrosion resistance, and high-temperature mechanical properties. The main raw material for this type of silicon carbide refractory material is a mixture of 98% silicon carbide powder and silicon carbide particles, usually 0-1mm in size. Some manufacturers also choose models such as 0.2-1mm and 1-2mm. Self-bonded refractory silicon refractory materials, such as refractory bricks, silicon carbide turbines, silicon carbide pump bodies, etc., generally have better comprehensive thermodynamic performance than refractory materials mixed with boron nitride or corundum.
