Pt-S (Platinum-Sulfur) H.F. Franzen Two compounds-PtS [60Gro, 66Kje] and PtS2 [65Fur]-are well established. The lattice parameters of PtS were reported for temperatures from 0 to 1000 C by [ 66Kje]. [66Kje] and [85Bry] agree that there is at most a narrow homogeneity range for PtS. The solubility of S in (Pt) is reported to be <0.01 wt.% [85Bry] . The assessed Pt-S phase diagram is based on the differential thermal analysis measurements of [85Bry] and their calculated liquidus curve. Using data from [74Mil] PtS2(s) was calculated to be unstable with respect to PtS(s) and S2 gas above about 727 C at P = 1 bar. 60Gro: F. Gronvold, H. Haraldsen, and A. Kjekshus, Acta Chem.
