Title:
PRODUCTION OF ALKALI METAL/METAL/HALIDE COMPOUND AND ALKALI METAL
Document Type and Number:
Japanese Patent JPS63121687
Kind Code:
A
Abstract:
A method of making an (alkali metal) (metal) halide compound and an alkali metal, the compound having the formula MDHalx+1 in which D is a metal; M is an alkali metal; Hal is a halide; and x is the valency of the metal D. The compound is made by exposing to one another a molten MDHalx+1 compound, a metal D and an alkali metal halide having the formula MHal. The MDHalx+1 compound is separated from a molten alkali metal M by means of a separator which is in contact with both the molten MAlHal4 and molten alkali metal. The separator can include a solid conductor of ions of the alkali metal or a micromolecular sieve having the alkali metal absorbed therein. A sufficient electrical potential is applied across the electrolytic cell D/MHal/MDHalx+1 PARALLEL separator PARALLEL alkali metal to cause the following reactions to take place: xMHal+D->XM+DHalx and MHal+DHalx->MDHalx+1. The alkali metal formed in the first reaction passes through the separator and into the molten alkali metal. The electrical potential is a direct current potential arranged so that electrons are fed via an external circuit into the molten alkali metal.
