摘要：

A solid state electrochemical technique was employed to study the dissociation oxygen partial pressures of DyFeO3 and Dy3Fe5O12 at elevated temperatures. The standard enthalpies ΔHof and entropies ΔSof of formation were obtained to be - 1349.7 kJ/mol and - 253.2 J/mol·K for DyFeO3 in the temperature range from 1173 to 1473 K, and - 4879.5 kJ/mol and - 1011.6 J/mol·K for Dy3Fe5O12 in the temperature range from 1173 to 1523 K, respectively. © 1979.
