Influence of the Evaporation Temperature and Degree of Distillation on the Effective Separation Factor

Inorganic Materials Aims and scope

Abstract—

We demonstrate the conceptual feasibility of step-by-step calculation of the effective separation factor β in distillation and sublimation processes as a function of the evaporation temperature T and degree of distillation g. The variation of β with T and g is thought to stem from the influence of T and g on the impurity distribution over the vaporizing material. The β(T) and β(g) dependences can be found using the Burton–Prim–Slichter equation and calculated impurity distributions in the vaporizing material at particular parameters of the substance and material. We present examples of such calculations for a beryllium-based model material.
