Description
Investigation on refining of rhenium of different initial purity of vacuum melting and zonal recrystallization were carried out. The rhenium purity was checked by the mass-spectrographic and chemical methods, and also by measuring the relative residual resistances. It is shown that the highest degree of purification is achieved by using initial rhenium obtained by hydrogen reduction after removal of low-volatility impurities. Single crystals of rhenium with a ratio of Rsub(298K)/Rsub(4.2K) exceeding 30000 and with a content of the main component of 99.9998 wt.% were obtained
