How much is the content of boron carbide in refractory material?
Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,
Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
furthermore, aluminite powder costs only ?20,000/ton, and the addition is only 0.1%—2%, or just none; while boron carbide costs ?50,000/ton.
