A new concept of a continuous reduction process for titanium production was discussed and experimentally verified. The new process employs molten alloy system containing titanium, zinc and magnesium. TiCl4 is injected into the molten alloy to be reduced by magnesium in the alloy. By using TiCl4 injection technology, the reduction process of high efficiency, which has following two advantages, was developed. 1) The reduction reaction can be carried out even in such a condition that magnesium content in the molten alloy is not higher than one percent. 2) Titanium production rate is increased to the level much higher than that of batch Kroll process.
