Platinum-Cadmium Alloys

Abstract

Platinum-cadmium alloys containing as high as 50 per cent platinum have been prepared by heating the two metals together. Solid platinum dissolves in hot molten cadmium to form a series of alloys, the melting points of which are relatively low. The thermal diagram of a portion of the system has been investigated by means of thermal analysis, microscopic study and X-ray examination. Two intermetallic compounds are formed, Pt2Cd9 and PtCd2. The compound Pt2Cd9 decomposes at a temperature of 615 into cadmium and PtCd2. The compound PtCd2 melts at 725°C. Pt2Cd9 and cadmium form a eutectic at 2 per cent cadmium which melts at 315°C.
