ABSTRACT:
A process for the production of non-metallic element Nm or a mixture/compound containing Nm from a non-metal halide NmX.sub.n or a coplex halide A.sub.m NmX.sub.o by electrolysis in a cell comprising an anode, a liquid metal cathode comprising one or more metals M and a liquid electrolyte comprising a salt melt of one or more alkali metal or alkaline earth metal halides, which comprises introducing non-metallic halide NmX.sub.n or complex halide A.sub.m MnX.sub.o, in which Nm represents a non-metallic element selected from the groups 3a, 4a, 5a and 6a of the periodic system, X represents halogen, n represents the valency of Nm, A represents an alkali metal and o represents the valency of Nm minus m, into the liquid metal cathode, and isolating Nm or a mixture/compound containing Nm from the metal cathode material.
