The graphite mold antioxidant is an oily liquid. Its effective component is high temperature resistant nano ceramic particles. In the oxidation environment where the use temperature of the graphite mold is less than 1300 ℃, its antioxidant effect exceeds.

Antimony impregnated graphite is an excellent self-lubricating and anti-wear material. It can be used at high temperature of 500 ° C, cryogenic temperature of - 253 ° C, high speed of 20000 rpm, high pressure of 10MPa, or high viscosity. It is especially suitable for working conditions of water, oil, kerosene and other media.

Antimony metal is insoluble in water, hydrochloric acid and concentrated alkali solution. Antimony rarely dissolves when it rubs with steel with increased load and speed. Therefore, antimony impregnated graphite materials are also suitable for water, hydrochloric acid, concentrated alkali and other media. The materials of antimony impregnated graphite may be silicon carbide, tungsten carbide or stainless steel.
