High-Temperature Mass Spectrometric Study of the WO3–ZnO System: Enthalpy of Reactions Involving Nonstoichiometric Phases
摘要
Abstract
The enthalpies of sublimation reactions of non-stoichiometric phases WO2.985(s) and ZnWO2.975(s) with the formation of gaseous oxides W2O6, W3O8, W3O9, W4O12 were obtained. It is shown that the difference with the enthalpies obtained without taking into account deviations from stoichiometry is significantly less than the uncertainties of the enthalpies caused by high-temperature mass spectrometry method.
