Anti-oxidation Treatment
Graphite antioxidant coating products are based on artificial graphite, and the surface of graphite products is treated with special coating, so as to improve the antioxidant capacity of graphite products and extend the service life. It is widely used in metallurgical mold, sintering mold, smelting crucible, impeller and rotor used in high temperature etc.. The service life of the graphite products with this composite coating on the surfaces is much longer than that of the ordinary graphite products (service life is about 3-5 times longer), which solves the problem that graphite products are easy to oxidize in high temperature environment.

The impregnation method is to impregnate graphite materials with oxidization-resistant materials to reduce the porosity of graphite products, so as to achieve the purpose of reducing the contact surface of carbon and oxygen, and improve the oxidation resistance of graphite materials. In order to achieve satisfactory results, different impregnation methods should be used according to the specific conditions of the impregnating agent.
Main features
1. High temperature antioxidant: when the temperature reaches 1600℃, the antioxidant performance is still very good.
2. High purity: obtained by chemical vapor deposition under the condition of high temperature chlorination.
3. Erosion resistance: high hardness, dense surface, fine particles.
4. Corrosion resistance: resistant to acid, alkali, salt and organic reagents.
5. The SiC surface layer is β-silicon carbide, which is face-centered cubic.
