摘　　要：在对钙熔盐电解过程中石墨阳极氧化机制分析的基础上,进行石墨阳极抗氧化研究。研制出适合于钙熔盐电解的石墨阳极抗氧化涂层,XRD和SEM分析及氧化失重试验结果表明,涂层致密无裂纹且附着力强。On the analysis of the oxidation mechanism of graphite anode in calcium molten salt electrolysis process, the resist-oxidation of the graphite anode is investigated. The protection coating used for graphite anode in calcium molten salt electrolysis is developed. It is indicated by XRD, SEM analysis and the weight loss experiment with oxidation that the coating is compact without crack and with strong adhesive, and with excellent capacity for oxidation protection of the graphite anode.
