Vaporization of Compounds and Alloys at High Temperatures. Part 17. Thermodynamic Study of Tin Selenide and Tin Telluride Using a Mass Spectrometer

Abstract

In a mass spectrometric investigation of the vapor in equilibrium with solid SnSe and solid SnTe, a number of reaction enthalpies were measured and from known thermochemical data, the following thermochemical values were calculated: enathalpy of formation at 298 degrees of SnSe and SnTe; dissociation energy of SnSe and SnTe; enthalpy of dimerization at 298 degrees of SnSe, SnTe, and SnTe2. The dissociation energies were compared to the available spectroscopic data.
