The phase diagram and thermodynamic data on the Sr–Cu–O system at a total pressure of 10 5 Pa (1 bar) have been reviewed and assessed. Gibbs energy functions for the ternary oxides Sr 2 CuO 3 , SrCuO 2 , Sr 14 Cu 24 O 41 , SrCu 2 O 2 , and the liquid phase have been optimized, and a consistent thermodynamic description is presented. Calculated SrOCuO x phase diagrams in air and in 1.01 ×10 5 Pa (1.01 bar) O 2 , the oxygen potential diagram, and various thermodynamic properties are shown and compared to experimental data.
