在850℃和470℃下，用真空石英玻璃管干电荷法、反射光学显微镜和显微探针法研究了铂-铁-砷-S相系。在850℃时，体系中存在四种熔体；(铂，砷)和(S，砷)熔体以及熔融的砷显示出除其基本组分外的极低的溶解度。第四，(Fe，As)熔体溶解高达24at%的铂。在二元相中，精铅矿占主导地位，高达25.3at%的S在固溶体中溶解砷
The phase system Pt-Fe-As-S was studied at 850°C and 470°C by means of dry charges in evacuated silica glass tubes, reflected-light microscopy and microprobe analyses. At 850°C, four melts are present in the system; the (Pt,As) and (S,As) melts as well as molten arsenic show very low solubility of other than their basic components. The fourth, (Fe,As) melt dissolves up to 24at%Pt. Among binary phases, sperrylite dominates the system, dissolving up to 25.3 at%S in solid solution for arsenic
