Detailed steps to remove impurities from silicon carbide products:
①First of all, let’s talk about the pickling of silicon carbide. Pickling is usually to treat silicon carbide particles with sulfuric acid under the condition of heating. The main purpose is to remove impurities such as metallic iron, iron oxide, magnesium, and aluminum in silicon carbide. In this way, impurities in silicon carbide can be removed very cleanly and quickly.  
②The second is the alkali washing of silicon carbide. The alkali cleaning of silicon carbide is usually treated with NaOH under heating conditions. The main purpose is to remove free silicon, silicon dioxide, etc. on the surface, which can increase the content of silicon carbide and strengthen its silicon carbide. content.
