AgSnO2电接触材料的研究进展

摘要

Content As a substitute of AgCdO material, AgSnO2 material is a new type non-toxic electrical contact materials that has developed very rapidly in recent years. The advantages and disadvantages of internal oxidation and powder metallurgy are simply introduced. After a comparison between the situation of contact material industry in China and foreign countries, the type, physical property and manufacturing process are discussed.%作为 AgCdO 材料的替代物，AgSnO2材料是近年发展很快的一种新型无毒电接触材料。简要分析了内氧化法与粉末冶金法制备 AgSnO2电接触材料的优缺点。通过对当前国内外电接触材料行业状况的对比分析，讨论了 AgSnO2电接触材料的品种、物理性能及相关制备工艺。
