The thermodynamic properties of BaY2O4

The standard thermodynamic functions of formation of BaY2O4 from simple oxi des were determined in the temperature range 1087-1265 K by the electromoti ve force method with a solid fluorine-ion electrolyte. The available data o n the thermodynamic properties of this compound were critically analyzed. N o deviations from stoichiometry exceeding the error of measurements, either in the ratio between the cations or in the content of oxygen, were detecte d for BaY2O4 under the conditions of our experiments.
