Abstract
The process which is the subject of this invention concerns the preparation of titanium by electrolysis from a bath of molten halides. It comprises effecting partial reduction of the TiCl.sub.4 which is used as the starting material in a separate reaction vessel, and then directly feeding the electrolyzing apparatus by means of titanium halides with a valency of less than 3. The partial reduction of the TiCl.sub.4 is effected by means of divided titanium or another metal such as Na.
