Production Technology Institute of the University of Tokyo in the medical grade titanium Valley Snow Yuki assistant with Professor Toru Okabe developed by recycling mixed with iron, oxygen, low-grade titanium scrap titanium production technology. In the smelting process of recycling, and scrap iron chloride for the reaction. Thus, the waste previously difficult to handle can be obtained by a combination of mutually valuable titanium.
Due to the presence of surface oxide titanium block after cutting, easily mixed with coolant and metal-cutting equipment and other issues, recycling more difficult. Therefore, the development of a low-grade titanium chloride reacted with the iron scrap, recycling processes titanium tetrachloride gas.
Titanium tetrachloride is reduced in the next process, thereby obtaining titanium. Ferric chloride is difficult to handle the waste generated during the smelting of titanium. Rational use of chlorinating agents can reduce costs, improve resource efficiency. All along, titanium scrap and iron chloride will react after the titanium surface covered with a layer titanium grade 5 of iron, titanium and ferric chloride lead to termination of the reaction. This time, to add magnesium chloride, samarium molten salt as a medium to make it happen with the titanium chlorination. Because of ferric chloride and titanium without the direct reaction, the reaction stops phenomenon and therefore does not appear.
