Black silicon carbide

Black silicon carbide is powdery black silicon carbide, according to customer requirements, black silicon carbide as raw material to grind into different granularity of black silicon carbide powder. In the production of silicon carbide, mainly quartz sand, petroleum coke, silica as raw materials, through the resistance furnace high temperature smelting. Black silicon carbide powder is a micron grade silicon carbide powder, mainly used in the abrasive industry, and its grade classification is very strict, no large particles are allowed to appear. Silicon carbide powder mainly black silicon carbide powder, green silicon carbide powder.

The silicon content in black silicon carbide directly determines the hardness of silicon carbide. The particle size of black silicon carbide powder has great influence on the wire cutting, but the important thing is the particle shape of silicon carbide. Because of the free state of silicon carbide cutting, black silicon carbide particle shape change has an important effect on the cutting efficiency and cutting quality. Black silicon carbide powder is mainly used for linear cutting of 3-12 inch monocrystalline silicon, polysilicon, potassium arsenide, and quartz crystals. Is the solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
