Abstract
In this study, LVE (liquid-vapor equilibrium) data of cadmium-zinc system were determined at pressure of 7.5 Pa. We compare the use of the Redlich-Kister polynomials with the Wilson equation in fitting activities. The LVE for Cd-Zn system in vacuum distillation was modeled using the two models. The results of the two models are reliable, the Redlich-Kister polynomialsis better than the Wilson equation. The LVE phase diagram is reliable for predicting the process of vacuum distillation for Cd-Zn system. Evaporation rates of elements in Cd-Zn alloy were experimental measured and calculated by the Langmuir equation. Experimental data on the evaporation of pure metals Cd and Zn are included. The evaporation coefficients of zinc and cadmium under vacuum conditions were calculated. The deviations were discussed. Comparing calculations with experimental results, it can be found that the trend is consistent. The activation energies of Cd and Zn in the Cd-Zn alloy under experimental conditions were also calculated.
期刊介绍：
University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded.
Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
