摘要：
The standard enthalpies of formation and standard entropies of Ln1.85Ce0.15CuO4 and Ln2CuO4 (Ln=Nd, Sm and Eu) were determined by the EMF method. It was found that Ln2CuO4 is more stable than CuO and the addition of CeO2 to Ln2CuO4 increases the chemical stability. The standard enthalpies of formation of Ln1.85Ce0.15CuO4 and Ln2CuO4 were calculated and compared with the data determined by calorimetry. Good agreement was found.
