中文摘要：

按一定比例配制6种不同的复合碱金属盐浸渍剂溶液，对炭阳极基体进行浸渍，探讨其抗氧化性能。测试了不同浸渍剂浸渍的炭阳极试样及未经浸渍的原试样的氧化度和热性能，并通过扫描电子显微镜（SEM）对其组织形貌进行了分析。结果表明：以试剂A为溶剂配制的浸渍剂溶液能够起到很好的抗氧化作用，其中以试剂A、2号Na盐和助剂B组合的浸渍剂效果最好，该浸渍剂浸渍过的炭阳极试样灼烧至800℃氧化度仅为19．7％，失重率也比原试样降低了68％。以硼酸为溶剂配制的复合碱金属盐浸渍剂反而会加剧炭阳极基体的氧化反应速率。试剂A为溶剂配制的复合碱金属盐浸渍剂在炭颗粒表面和空隙间均匀分布，不仅能够延缓氧化反应速度，而且还能提高炭阳极材料剧烈氧化的初始温度。

英文摘要：

Carbon anode are impregnated by different compound alkali metal salts, prepared with certain proportion. Oxidisation degree and thermal property of the carbon anodes which were dipped by different impregnant or untreated were tested, while the microstructures and morphologies of samples were analyzed by SEM observation. The results show that impregnant, with reagent A as solvent, can protect the matrix well. On the contrary, that with boric acid as solvent will aggravate oxidation reaction of the samples. Moreover, the oxidization degree of carbon anode, immersed by the best mix containing reagent A , the second sodium salt and addition agent B, is only 19. 7% and the hot weight loss is lower 68% than that of the untreated one. At the same time, impregnant, with reagent A as solvent, which distributes evenly on the surface and void of carbon particles not only decreases the rate of oxidation, but also increases the temperature of initial acute oxidation.
