Electrodeposition of Metals from Organic Solutions

Abstract

The electrodeposition of Mg from ether solutions of such Mg compounds as (a) halides, (b) aluminohydrides, (c) borohydrides, and (d) Grignard reagents was investigated. White, metallic deposits containing 90% Mg and 10% B were obtained from an ether solution of MgBr2 and LiBH4. However, thick deposits could not be built up. An alloy (7% Mg, 93% Al) was obtained from a bath containing MgBr2, AlBr3, and LiAlH4. Electrodeposited alloys of Zr, Ti, or Be with Mg, obtained from hydride or borohydride baths, were stressed, treed, or powdery. The preparation and solubilities of some of the solutes are given.
