thermodynamic properties - Opis:
- A new method for description of thermodynamic properties of Cu-S mixtures is put forward. The basic feature of this method is the assumption that the activity coefficient of sulphur dissolved in liquid copper is equal to 1 for infinite dilute solution (y[S] = 1 for x[S] = 0). In consequence the following relationships were established: 1. The equilibrium constant for the reaction of sulphur dissolution in liquid copper (0.5S2 (g) = [S] Cu ): [wzór]. 2. Non-temperature dependence of the activity coefficient of sulphur dissolved in the copper-reach liquid (Liquid I): lnγ[S] =-18.25 · x[S] . 3. The chemical potential of the sulphur dissolved in copper in infinite dilute solution: [wzór]. 4. Non-temperature dependence of the activity of sulphur in Cu-S sulphur-rich liquid (Liquid II) – Fig. 6. 5. Non-temperature dependence of the activity of copper in Cu-S sulphur-rich liquid (Liquid II) – Fig. 7. 6. The equilibrium constant for the reaction of sulphur removal from liquid copper ([S] Cu + 2[O] Cu = SO2 (g)): [wzór].
