THERMODYNAMIC CALCULATION OF PHASE EQUILIBRIA IN THE Cu-Y-O SYSTEM

摘要

Based on the available experimental data, thermodynamic evaluation of the Cu-Y-O system was performed. The thermodynamic functions of the phases present in this system were used to locate invariant points,and the projection of the liquidus surface was calculated.The log p(O_2)-T diagram of the Cu-Y-O system and the phase diagram of the CuO-YO_1.5 system at an oxygen pressure of 21 kPa were constructed.
