Abstract
Vaporization of GeO2 (tetragonal and hexagonal) have been studied by the Knudsen effusion method in combination with mass spectrometry in the temperature range 1250–1370 K. It has been demonstrated that the saturated vapor over GeO2 consists of GeO and O2 molecules. Partial pressures of the equilibrium vapor components and their temperature dependences have been determined. The standard enthalpy of the heterogeneous reaction GeO2(s) = GeO(g) + 1/2O2(g) and the standard enthalpy of formation of GeO2 (∆fH\(_{{298}}^{^\circ }\)(GeO(g)) = −41.7 ± 17.6 kJ mol–1) have been determined by the second- and third-law calculations.
