PROCESS FOR THE PREPARATION OF TRANSITION METAL POWDERS BY ELECTROLYSIS IN MOLTEN SALT BATHS

摘要

P The invention relates to a process for the preparation of transition metal powders by electrolysis in molten salt baths. This process is characterized in that the electrolysis is carried out in such a way that the deposition voltage of said transition metal is 0.1 to 0.4 volts lower than that of the easiest alkali or alkaline earth metal reduce. BR/ It finds its application in the preparation of powders of dimensions between a few fractions of microns to about 200 microns of metals belonging to columns IVb, Vb, VIb of the periodic table such as for example titanium, zirconium, hafnium. /P
