Thermodynamic Calculation of Phase Equilibria in the Ba-Be-O System

摘要

Thermodynamic assessment of the Ba-Cu-O system is carried out, an the coordinates of invariant equilibria are determined. The BaO-CuO phase diagram at oxygen pressures of 21 and 100 kPa, the log p (O_2) -T diagram of the Ba-Cu-O system, and the projection of the liquidus surface of the Ba-Cu-O sys- tem are calculated. The results are compared with the available experimental data.
