摘要: An extension of the associated solution model is developed and applied to Cu-O liquid phase. Associated species “Cu2O” in are assumed, which interact with surrounding free Cu O atoms. All thermodynamic properties phase diagram calculated from this good agreement experimental information. The success mathematical description is, course, no proof for physical existence species. A consistent set data various solid, liquid, gaseous phases given by comprehensive evaluation. In addition, linear approximations Gibbs energies reaction formation interaction coefficients offered. metastable liquidus compound CuO at elevated pressure predicted, congruent melting point being 1228 °C δC atP O 2 = 24.4 atm (2.47 MPa).
