Resumo
Using the method of direct synthesis calorimetry, we determined the standard enthalpy of formation of PtSb (stumpflite), ΔfH°298.15 (PtSb, cr) =–105.16 ± 0.84 kJ/mol and PdSb2 (geversite), ΔfH°298.15 (PtSb2,cr) =–160.92 ± 0.84 kJ/mol. Isothermal (298.15 K, p = 1 bar) phase diagrams were computed for the Pt–Sb–S and Pt–Sb–O ternary systems in the coordinates composition of the Pt–Sb binary system versus fugacity of a gaseous volatile component (O2, S2).
