PROCESS FOR THE EXTRACTION OF RELATIVELY PURE TITANIUM AND OF RELATIVELY PURE ZIRCONIUM AND HAFNIUM
A process for producing relatively pure Ti, Hf, or Zr metal is based on electrolytic deposition of metal in an electrolytic cell having a consumable anode made of carbide of the metal. The electrolytic bath is composed of fused salt, which is the halide of a metal selected from the group consisting of the alkali metals and alkaline earth metals including Mg and mixtures of such halides. Addition of a small amount of double halide of alkali metal and the metal in question accelerates the process, produces purer metal, and makes larger crystals. The temperature of the bath should be over 800 deg C, preferably 850 deg C. An apparatus in which the process can be carried out is illustrated, and examples of the process are given. (A.G.W.)
