摘　　要：含炭耐火材料在高温下易被氧化 ,从而造成材料性能急剧下降。靠浸渍溶液或在基质中添加抗氧化剂已不能满足工业发展及某些特殊场合的要求。文章通过对多种氧化物及非氧化物原料的特点进行分析 ,探讨了研制的自愈合系列高温抗氧化涂料 (RefractoryAnti OxidationCoating ,RAOC)的抗氧化机理。Carbon containing refractories are easily oxidized at high temperature, resulting in the service properties rapidly dropping. The anti oxidation methods, such as impregnation and adding anti oxidation agents, can't meet the requirement of industry development and some special cases. By analyzing the characteristics of several oxides and non oxides raw materials, the oxidation resistant mechanism of the anti oxidation coatings(ROAC), which possess the characteristic of self healing at high temperatures, is discussed.
