IPC: C22C5/06
Filed: 1993-12-27
Abstract: PURPOSE:To obtain the silver-tin oxide contact material excellent in contact property and cold workability by minutely/uniformly dispersing a tin oxide grain of the specific content in Ag matrix through chemical coprecipitation method and powder sintering method. CONSTITUTION:An silver nitrate solution (acid solution) and tin oxide sodium solution (alkaline solution) are simultaneously mixed or simultaneously dripped in the water matrix prepared for pH so as to be added/mixed. Thus, after the precipitate generated/precipitated in the mixed solution is recovered and cleaning/dehydrorating treatment are repeated, it is processed by drying at about 600 deg.C. By this method, the mixed powder which consists of 5-40wt.% tin oxide and the balance silver and the tin oxide having a grain size of <=0.5mum preferably <=0.3mum is minutely/uniformly dispersed in Ag matrix, is obtained. Subsequently, this mixed powder is compacted to be sintered in atmosphere at about 800-900 deg.C. Further, the sintered body is subjected to hot extrusion and then the silver-tin oxide contact material is obtained through drawing or rolling.
