Thermodynamic, Structural and Transport Properties of Molten Copper-Thallium Alloys

A self-association model has been used to understand the concentration dependence of free energy of mixing (GM), heat of mixing (HM), entropy of mixing (SM), activity (a) and microscopic structures, such as concentration fluctuation in long wavelength limit (Scc(0)) and Warren-Cowley short range order parameter ( 1 α )for CuTl molten alloys at 1573K. A comparative study of surface tension of th...

Thermodynamic Investigation of Copper Removal From Liquid Slag.

The removal of copper dissolved in liquid stags by pyrometalIurgical means such as gaseous reduction and sulfidization is thermodynamically investigated. The lowest level possible for copper content is theoretically determined and compared. The results show that gaseous reduction is not as effective as sulfidization. Slags with very low levels of dissolved copper can be obtained with sulfide tr...
