The results from a new method for preparing very pure metals and applications of this method for refining beryllium, iron, manganese, chromium, etc., are outlined. The method differs from the conventional methods of vacuum distillation of metals in that the surfaces heated to high temperatures are used as condensers. The possible kinetics of the process of removing slight impurities during the condensation on surfaces with a high temperature points to the possible refining of metals from impurities whose vapor pressure differs from that of the base metal. An illustration is given of refining beryllium from an admixture of manganese and aluminum, as experimental proof of the procedure. The data obtained indicate that it is possible to obtain beryllium 99.98% pure at d commercial scale processes. Similar data are given with respect of iron and manganese. Iron crystals obtained by condensation on a surface with a temperature of 1150 deg C are 99.996% pure. These iron samples are the purest obtained in laboratory conditions. A single distillation of ferromanganese produces a manganese condensate 99.98% pure. Distillation of chromium is given as an example to prove the necessity of taking into account additional factors affecting the purity of the metal to be produced. These factors are the formation of volatile suboxides during the evaporation and the reduction of activity'' of some elements in the presence of slight impurities. Further possible applications of the new method for refining metals from slight impurities are discussed. (auth)
