Abstract

The standard thermodynamic properties of Ca₃TeO₆were determined electrochemically utilizing fast O^2- ion conducting solid electrolyte yttria-stabilized zirconia. The ternary phase was synthesized from the pure oxides CaO and TeO₂ in excess of CaO. The electromotive force measurements were performed on two similar electrochemical cells of the type Te-CaO-Ca₃TeO₆ | YSZ | O₂, within the temperature range from 850 to 949 K. The standard Gibbs energy of formation for the ternary compound Ca₃TeO₆ was determined for the first time, based on the experimental data obtained.
