It is shown that the electrochemical reduction of zirconium dioxide in molten electrolyte mixtures that are based on calcium and magnesium compounds on a liquid gallium cathode can be used to obtain a finely divided zirconium powder of high purity. The recovery degree depends on the cation composition of the electrolyte mixture. The best performance is provided by a melt based on compounds of calcium and sodium chloride.
