Abstract
A high valency salt, such as TiCl.sub.4 is reduced to a lower valency salt, such as TiCl.sub.2 and/or TiCl.sub.3 within a fused salt electrolytic bath via electrolysis so that an improved electrodeposition of a desired metal or alloy, such as Ti, occurs, from such adjusted bath. The process generally comprises adding a higher valency salt of a desired metal or alloy to a fused salt electrolytic bath, reducing the higher valency salt on a cathode electrode to a lower valency salt, removing the so-produced lower valency salt from the electrode surface and maintaining a predetermined amount of the lower valency salt within the electrolytic bath. Electrodeposition of a desired metal or alloy may then take place from such electrolytic bath containing a so-adjusted amount of the lower valency salt.
