The carbon anti-oxidation coating for aluminum electrolysis is manufactured using a core technology in which micron-scale ceramic powders are modified with a polymer-based metallic binder. The product can cure at ambient temperature within 12 to 72 hours. It is easy to apply and features strong adhesion, excellent penetration, and good film-forming properties. This non-toxic inorganic coating is suitable for high-temperature smelting applications involving graphite electrodes and carbon materials used in aluminum electrolysis. Pre-sintering can be completed at 300°C to 500°C, and the coating can withstand prolonged exposure to temperatures above 900°C, while resisting attack from high concentrations of carbon dioxide, hydrogen fluoride, and oxygen. It effectively isolates conductive graphite and carbon materials from high-temperature oxidation. After 72 hours of calcination in air at 900°C, the weight loss rate is approximately 1%.
