ABSTRACT:
A novel method of producing a silver, tin-indium oxide contact material is disclosed. The material is fabricated by alloying silver with tin and indium, hermetically joining two sheets of such alloy with a layer of release material therebetween to form a multilayer structure, internally oxidizing the structure at elevated pressure and separating it into component parts. The inventiive process produces a member substantially free of oxide depleted regions about at least one surface.
