How to improve the purity of silicon carbide?: Impurities of silicon carbide powder will affect the range of use of silicon carbide, reduce the price and quality of silicon carbide. Silicon carbide ultrafine powder has high melting point and hardness, relatively stable chemical and physical properties. High-purity ultra-fine silicon carbide powder is widely used in modernization, industrialization and other fields, but silicon carbide in smelting or processing is easier to introduce impurities, iron oxide iron is one of them.How to improve the purity of silicon carbide?
How to improve the purity of silicon carbide?: The advantage of the chemical method of removing iron in the ultrafine silicon carbide powder is relatively clean, but the silicon carbide treated by the chemical method is easy to caking, and the method is more complex. The physical method of removing iron in silicon carbide ultrafine powder, mainly using mechanical physical iron removal method, the need to use magnetic separator equipment, the use of magnet principle to collect iron impurities in silicon carbide ultrafine powder, magnetic separator equipment has different specifications, the collection effect is different, the use of magnetic separator method is more convenient and fast, only need to buy equipment can, However, the use of magnetic separator iron removal effect is limited, can only improve the purity of silicon carbide, so that its use standards qualified, and can not completely remove iron, the need for higher purity silicon carbide powder products, you can repeatedly magnetic separation or the use of chemical methods to remove iron, hope to increase the purity of silicon carbide to reduce iron carbide can use physical magnetic separation equipment.How to improve the purity of silicon carbide?
