Electromotive force measurements in liquid K–Te solutions with a potassium β alumina electrolyte

Thermodynamic properties and phase relations of K–Te alloys were measured over a temperature range of 573–873 K and over the composition range 0–55 at. % K. An electromotive force (emf) technique was used in which potassium-substituted beta alumina served as the solid electrolyte. Partial and integral values of Gibbs energy, entropy, enthalpy, excess stability, and excess heat capacity are reported. The excess stability function exhibits maxima …
