Abstract

By studying the heat treatment of metallic germanium obtained from mineral raw materials, in is experimentally established that germanium heating in a certain narrow temperature range leads to a significant decrease in the concentration of uncontrolled impurities. The use of such a heating as a preliminary germanium purification makes it possible to increase significantly the efficiency of subsequent germanium purification by a zone melting method.

Keywords: Germanium; Purification; Volatile impurities; Zone melting
