OBTAINMENT OF DISPERSION METAL POWDERS BY ELECTRO REDUCTION OF DIFFICULT SOLUBLE COMPOUNDS IN MOLTEN MEDIA

The possibility of obtaining metal powders of Co, Ni, Fe, Mo, V, and others from difficultly reducible oxides with the aid of intermediate reagents in molten electrolyte, is shown. The dependence of current output upon temperature and current density during the reduction of iron oxides is explained....

Description
Summary:The possibility of obtaining metal powders of Co, Ni, Fe, Mo, V, and others from difficultly reducible oxides with the aid of intermediate reagents in molten electrolyte, is shown. The dependence of current output upon temperature and current density during the reduction of iron oxides is explained. It was established that the powders so obtained have, basically, a dendritic form and that the dimensions of the particles are in the range of 10-30 microns, thus making them suitable for the manufacture of ceramet objects.
