在C(s)/CO(g)平衡的氧分压下，用ti3o5平衡Cu-Ti液体，测定了1623和1673 K时钛在Cu-Ti液体中的活度系数。此外，通过平衡58质量，测定了1773 K时硅与钛的热力学相互作用参数和钛在Cu-Ti-Si液体中的自相互作用参数% TiO2-42 mass% CaF2slag with Cu-Si-Ti liquids. And the interaction parametersandobtained using a multiple regression were as large as −69.32 and 15.44 respectively. Based on the above determined value of, the relationship between Henrian constant of titanium in liquid Cu-Ti melt, $$ \upgamma_{{{\text{Ti}}({\text{s}})}}^{0} $$, from 1473 to 1923 K was evaluated, and is expressed as:$$ \ln \,\upgamma_{{{\text{Ti}}({\text{s}})}}^{0} = 14.09 - \frac{25742.1}{T} $$The Gibbs energy of dissolution of solid titanium into liquid copper relative to 1 mass% state in the temperature range from 1473 to 1923 K can be expressed as:$$ \Updelta_{\text{sol}} G_{{\% ,{\text{Ti}}({\text{s}})}}^\circ = - 214019.82 + 81.21T\;{\text{J/mol}}. $$
The activity coefficients of titanium in liquid Cu-Ti at 1623 and 1673 K were measured by equilibrating the liquids with Ti3O5in a oxygen partial pressure controlled by C(s)/CO(g) equilibrium. Furthermore, the thermodynamic interaction parameter of silicon on titanium and the self-interaction parameter of titanium in liquid Cu-Ti-Si at 1773 K were determined by equilibrating the 58 mass% TiO2-42 mass% CaF2slag with Cu-Si-Ti liquids. And the interaction parametersandobtained using a multiple regression were as large as −69.32 and 15.44 respectively. Based on the above determined value of, the relationship between Henrian constant of titanium in liquid Cu-Ti melt, $$ \upgamma_{{{\text{Ti}}({\text{s}})}}^{0} $$, from 1473 to 1923 K was evaluated, and is expressed as:$$ \ln \,\upgamma_{{{\text{Ti}}({\text{s}})}}^{0} = 14.09 - \frac{25742.1}{T} $$The Gibbs energy of dissolution of solid titanium into liquid copper relative to 1 mass% state in the temperature range from 1473 to 1923 K can be expressed as:$$ \Updelta_{\text{sol}} G_{{\% ,{\text{Ti}}({\text{s}})}}^\circ = - 214019.82 + 81.21T\;{\text{J/mol}}. $$
