FREMSTILLING AV MODERLEGERINGER AV JERN OG NEODYM VED ELEKTROLYSE AV OKSYGENHOLDIGE SALTER I SMELTEDE FLUORIDER.

摘要

The invention relates to a method of preparation of a mother electrolytic alloy of iron and of neodyme by reduction of a mixture comprising at least one oxygen reactant is composed of neodyme in a bath of molten halides with at least one metallic cathode then in iron and a carbon anode. / p & & p & according to the invention, 1 / p & & p & - the bath is constituted principally of a mixture of molten fluorides, the potential of decomposition is close to that of the electrolysis or more negative, such as, for example, electrolysis, mgf, iaf, baf, caf, srfi of solubilization of the oxides. / p & & p & - the solute has reduce is constituted by a mixture of salts containing mainly composed of the oxygen reactant neodyme very rapidly, which is soluble in the molten electrolyte. / p & & p & the temperature of the work is stiue in a range of 640 a 1030 c. / p & & p & - the cathode current density is preferably from 0,1 to 1,5 acm2. / p & & p & - the anodic current density is between 2 and 30 acm.
