METHOD OF REFRACTORY METALS AND ALLOYS PURIFICATION FROM NON-FERROUS METAL IMPURITIES

摘要

Usage: plasma metallurgists and receiving refractory metal (such as fovolfram, molybdenum, etc.) And precision alloys. Summary of the invention: the method for purification of refractory metals and alloys of non-ferrous metal impurities treatment is carried out over the entire surface of the melt processed material discharge by providing a melt using as a negative electrode and by passing therethrough a current with a current density of at least 1 A / cm2. 1 ,, yl Table 2.
