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 PtCd_2. The compound PtCd₂ melts at 725°C. Pt₂Cd₉ and cadmium form a eutectic at 2 per cent cadmium which melts at 315°C.
