The silicon boride is glossy black-gray powder, the relative density of 3.0 g/cm, melting point :2200 ℃, The grinding efficiency is higher than boron carbide and silicon carbide. It is insoluble in water, resistant to oxidation, thermal shock and chemical erosion etc.Especially has high strength and stability under thermal shock.
◆ Silicon boride can be used as standard grinding materials , which used for grind hard materials such like: hard alloy and sapphire etc…
