Abstract

Способ получения Ti включает восстановительный этап взаимодействия TiClс Са в CaCl-содержащем солевом расплаве, содержащем растворенный в нем Са, чтобы таким образом образовать частицы Ti, разделительный этап отделения частиц Ti, образованных в упомянутом солевом расплаве, от упомянутого солевого расплава, и электролизный этап проведения электролиза солевого расплава для того, чтобы повысить концентрацию Са, при этом солевой расплав с повышенной концентрацией Са на электролизном этапе вводят внутрь регулировочной ячейки, чтобы таким образом сделать концентрацию Са в солевом расплаве постоянной, и затем солевой расплав применяют для восстановления TiClна восстановительном этапе. В настоящем изобретении можно подавить колебание концентрации Са в солевом расплаве, подаваемом в соответствующий восстановительный сосуд, и, в то же время, поддержать высокие уровни концентрации. К тому же, непрерывно может обрабатываться большой объем солевого расплава. Поэтому реакция восстановления TiClможет быть осуществлена эффективно, и способ может быть эффективно использован в производстве Ti восстановлением Са как способ производства для осуществления производства Ti в промышленном масштабе.The method for producing Ti includes a reducing step of reacting TiCl with Ca in a CaCl-containing molten salt containing Ca dissolved therein to thereby form Ti particles, a separating step of separating Ti particles formed in said molten salt from said molten salt, and an electrolysis step molten salt electrolysis in order to increase the Ca concentration, while the molten salt with the increased Ca concentration in the electrolysis step is introduced into the control cell to thereby make the Ca concentration in the molten salt constant, and then the molten salt is used to reduce TiCl in the reduction step. In the present invention, it is possible to suppress fluctuations in the concentration of Ca in the molten salt supplied to the corresponding reduction vessel and at the same time maintain high concentration levels. In addition, a large volume of molten salt can be processed continuously. Therefore, the TiCl reduction reaction can be carried out efficiently, and the method can be effectively used in the production of Ti by the Ca reduction as a production method for carrying out the production of Ti on an industrial scale.
