| Outline of Final Research Achievements |
This study develops an environmentally friendly recycling process capable of recovering titanium tetrachloride by combining titanium metal scrap and iron chloride waste. The direct reaction between titanium and ferrous chloride is considerably slow between 1000 and 1200 K, and it is difficult to recover titanium tetrachloride effectively because solid iron produced by this reaction forms a rigid covering on the scrap surface. In order to overcome the drawbacks of this direct reaction, an efficient chlorination technique based on a reaction-mediating molten salt is devised, and its feasibility is demonstrated though thermodynamic analyses and fundamental experiments.
