The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。
