Black silicon carbide abrasive

Black silicon carbide abrasive is made of quartz sand, stone tar or anthracite as the main raw material, and is smelted at high resistivity. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum. It is brittle and sharp. Has a certain degree of electrical conductivity and thermal conductivity. It is used to make abrasive tools, which is suitable for processing metal and non-metal materials with low tensile strength. Such as gray cast iron, non-ferrous metals, stone, leather, rubber, etc. It is also widely used in refractory materials and metallurgical additives. The high-purity product of black silicon carbide with special treatment has higher strength and stronger grinding ability.
