The phase diagram and thermodynamic data on the Sr-Cu-O system at a to
tal pressure of 10(5) Pa (1 bar) have been reviewed and assessed. Gibb
s energy functions for the ternary oxides Sr2CuO3, SrCuO2, Sr14Cu24O41
, SrCu2O2, and the liquid phase have been optimized, and a consistent
thermodynamic description is presented. Calculated SrOCuOx phase diagr
ams in air and in 1.01 x 10(5) Pa (1.01 bar) O-2, the oxygen potential
diagram, and various thermodynamic properties are shown and compared
to experimental data.
