PRODUCTION OF PURE ALLOY BASED ON RARE EARTH METAL AND TRANSITION METAL BY HEAT-REDUCTION OF METAL

摘要

P industrial process for obtaining them, then without coulee, ingots of alloy - mother high — purity is at least one rare earth and of at least one transition metal, by reduction metallothermal of a compound of said rare earth by means of a reducing agent, such as the alkali metals or alkaline - metal, characterizes in that the transition metal is introduced into the starting reaction mixture of at least in part in the form of a compound reducible by the reducing agent used. / p
