Abstract

The Gibbs free energy, enthalpy, and entropy of the formation of Er2Ge5, ErGe2, ErGe2-b(ErGe1,5), Er3Ge4, ErGe, Er11Ge10, Er5Ge4, and Er5Ge3 from solid components are determined by measuring the electromotive forces of high-temperature galvanic cells. The maximum thermodynamic stability is shown by Er5Ge3,which is the only congruently melting compound in the Er–Ge system.
