The common method of silicon carbide production is to mix quartz sand with coke, use the silica and petroleum coke, add salt and wood chips, put in the electric furnace, heated to about 2000°C high temperature, after a variety of chemical processes to get silicon carbide powder.
Silicon carbide has become an important abrasive because of its great hardness, but its application scope is more than the general abrasive. Silicon carbide smelting block must be prepared first to prepare silicon carbide products. In industrial production, silicon carbide smelting block is usually quartz, petroleum coke as raw materials, auxiliary recovery material, waste material, after grinding and other processes to become a reasonable proportion and appropriate particle size of the charge prepared by high temperature.
The price of silicon carbide is determined by the size of silicon carbide and the complexity of the production process. The finer the size of silicon carbide, the higher the price
