PROCESS FOR PRODUCING Ti OR Ti ALLOY, AND PULL-UP ELECTROLYSIS METHOD APPLICABLE TO SAID PROCESS

WIPO Patent Application WO/2006/103944

A1

In the production of Ti or a Ti alloy by reduction of Ca, a bath salt withdrawn from the step of reduction is electrolyzed, and Ca and the bath salt are recovered as a solid which is then transferred to the step of reduction. According to this process, the latent heat of fusion possessed by the solid can be utilized to suppress the generation of heat in the step of reduction and thus to significantly improve the production efficiency and the thermal efficiency. At the same time, the reaction temperature can easily be controlled, and, thus, the starting material charge speed can be increased to produce Ti or Ti alloy with good efficiency. In this case, the use of a pull-up electrolysis method can realize the production of solid Ca and bath salt at low voltage with high current efficiency and, thus, with relatively low power consumption. When the solid Ca and bath salt are used as a Ca source in the production of Ti or Ti alloy by Ca reduction, Ti or Ti alloy can be produced with high efficiency.
