Thermal stabilities and properties of equilibrium phases in the Pt-Te-O system
Abstract
<p>Oxides and intermetallic phases in theplatinum-tellurium-oxygen system have been studied. Thermal stabilities,thermodynamics, and structures of the phases reported in theliterature, including the conditions under which PtO<sub>x</sub> formand decompose, have been compiled and critically evaluated. Heatcapacities of the binary phases have been estimated, and compared withthe scarcely available experimental literature data. The estimatedvalues are generally in agreement with the few available literaturedata.</p><p>The intermetallic phase PtTe was synthesized,and thermally analyzed by the differential scanning calorimetry andthermogravimetry techniques, under both inert and oxidizing conditions.Based on the calorimetric measurements, the <em>solidus</em> and <em>liquidus</em> temperatures, and enthalpy of melting of PtTe in the phase regionPtTe-Pt have been determined. For the first time, the maximum thermalstability of PtTe in an oxidizing atmosphere, close to the partialpressure of oxygen in air, is experimentally determined to be <em>T</em> = (603 ± 1) K, above which it oxidizes to form TeO<sub>2</sub> and Pt. Based on experimental observations in this work combined withthe literature review, isothermal ternary phase diagram of the Pt-Te-Osystem is proposed.</p>
