MANUFACTURING METHOD FOR A REDUCING METAL AND AN ELECTROLYTIC APPARATUS TO BE USED IN THE SAME

摘要

Disclosed are a method to efficiently manufacture, through molten salt electrolysis, a reducing metal suitable for the reduction reaction of titanium tetrachloride or titanium, and a molten salt electrolytic apparatus to be used in the same. The disclosed method of manufacturing a reducing metal involves filling a molten salt electrolytic cell with an electrolytic bath comprising a chloride of a reducing metal, immersing the anode and the cathode, and performing molten salt electrolysis; wherein: the electrolytic cell is divided into an anode chamber and a cathode chamber using a partition, and an extraction pipe for the produced metal is immersed in the cathode chamber. The metal produced in the electrolytic bath within the cathode chamber rises and forms a layer of reducing metal, which is kept at a constant thickness, while the reducing metal within the reducing metal layer is continuously extracted through the extraction pipe. Also disclosed is a molten salt electrolytic apparatus to be used in the manufacturing method of this reducing metal.
