Silicon carbide micro powder

Silicon carbide micro powder is made from silicon carbide by crushing equipment. However, in the process of smelting and crushing silicon carbide, it is inevitable that various impurities will be mixed in. These impurities will have a great impact on the quality of the products processed and the performance of the semiconductor devices manufactured during the use of silicon carbide powder, increasing the rate of defective products and reducing the surface processing quality of the processed products. Therefore, the problem of removing impurities in silicon carbide powder must be solved.

The impurities of silicon carbide powder mainly include carbon, ferric oxide, aluminum oxide, calcium oxide, magnesium oxide and silicon dioxide. When these substances are used for different purposes in silicon carbide powder, they have different effects, among which Fe2O3 is the main one. In order to remove impurities in silicon carbide powder, acid can be added to remove impurities in the production process. This method has low cost and high impurity removal rate, which is loved by silicon carbide powder manufacturers.
