How to remove impurities in silicon carbide products?: The use of acid cleaning method, acid cleaning can be very convenient to clean the impurities in silicon carbide, its operation method is also very simple, that is, in the condition of heating, with sulfuric acid to silicon carbide for appropriate help, so that sulfuric acid will react with the iron in silicon carbide, thereby removing the impurities. At the same time, impurities such as iron oxide and aluminum will also react with sulfuric acid, which can be well eliminated. There is also the method of alkali cleaning to remove, the alkali washing method of silicon carbide is relatively simple, it is also very similar to the pickling method, that is, under the condition of heating with sodium hydroxide for silicon carbide treatment, the main purpose is to remove the appearance of free silicon, silicon dioxide and so on, so that the content of silicon carbide can be improved, so that the content of silicon carbide can be increased. Therefore, the removal method of impurities in silicon carbide products is very simple, with pickling or alkali washing method can be very good to remove the different impurities, which can make the purity of silicon carbide products to improve, so as to have a better performance, and be important in more fields.
