Preparation of High-Purity Titanium by Molten-Salt Electrolysis Process

Abstract:

Titanium sponge is used as anode, titanium plate as cathode and NaCl-KCl-TiClx molten salt as electrolyte, to prepare high purity titanium by molten-salt electrolysis at 900~980°C. The effects of feeding TiCl₄ temperature, electrolytic temperature, soluble titanium concentration and cathode current density on the content of impurities of cathode products have been studied. The results show that the impurities in product can be controlled when the temperature of feeding and electrolyte is higher. The final product with different morphology and degree of purity can be prepared by controlling the soluble titanium concentration and cathode current density.
