Calculation of high-temperature sublimation refining in relation to the degree of sublimation for a material consisting of separate parts

详细

This paper considers high-temperature sublimation of a two-component material consisting of parts differing in size. A sublimation equation is used to calculate the average impurity concentration in the condensate as a function of the degree of sublimation. The results demonstrate that the sublimation refining of a multipart material can be both more effective and less effective than the sublimation of a material in the form of a single block, depending on process and material parameters, but the difference between the purity levels achieved is not very large.
