Abstract

Thermodynamic functions E 3000Thermodynamic Properties of Nd1+xBa2-xCu3Oy Compounds and Their Application for Optimizing the Synthesis of Superconducting Materials. -Standard enthalpies of formation, absolute entropies, and the temperature dependence of heat capacities in the range 5-1300 K are obtained for the title compound (x = 0-0.8, y = 6.65-7.24) using solution calorimetry, adiabatic calorimetry, and quantum chemical estimation methods. The conditions for synthesis of the superconducting NdBa 2 Cu 3 O 6.9 phase are determined using these data. -(ZELENINA*, L. N.; CHUSOVA, T. P.; MATSKEVICH, N. I.; NAUMOV, V. N.; STENIN, Y.
