Abstract (en)
[origin: WO8704193A1] The disclosed process is characterized in that the electrolysis is conducted in such a way that the voltage of deposition of said transition metal is lower by 0,1 - 0,4 volt than that of the alkaline or alkaline earth metal which is the easiest to reduce. The process may be applied to the production of powders whose sizes range from a few fractions of microns to 200 microns approximately of metals pertaining to the columns IVb, Vb, VIb of the periodic classification such as for example titanium, zirconium, hafnium.
