Abstract:The isoactivity of [Ce] of samples in multiple-hole graphite crucibles can be reached by con-trolling the equilibrium oxygen potential of the reaction 2[Ce]+ 3CO=Ce2O3 + 3C with C-CO.Using this principle and conjugate gradient method of solving illconditioned equations , the activi-ty interaction coefficients between Ce and Sn . Zn . Pb alloying elements were determined. The e-quilibrium constant of the reaction 2[Ce]+3[O]=Ce2O3 and the standard free energy of forma-tion of Ce2O3 in liquid Cu were obtained at 1200 ℃ .

 

Key words: Cu-Ce-M(M=Sn ; Zn ; Pb) liquid solutions thermodynamic properties
