Abstract

Настоящее изобретение предусматривает способ электролиза расплавленной соли, который может повысить концентрацию образующего металлический туман металла в расплавленной соли посредством осуществления электролиза, при условии, что расплавленная соль, содержащая хлорид образующего металлический туман металла, подается с одного конца электролитической ячейки в пространство между анодом и катодом непрерывным или периодическим образом для обеспечения скорости потока в одном направлении для расплавленной соли вблизи поверхности катода и, таким образом, для того, чтобы сделать возможным протекание расплавленной соли в одном направлении вблизи поверхности катода. По настоящему изобретению, в то время как поддерживается высокая эффективность тока, только расплавленная соль, обогащенная образующим металлический туман металлом, таким как Са, может эффективно отбираться. Кроме того, этот способ может легко осуществляться посредством использования электролитической ячейки по настоящему изобретению. Кроме того, применение способа электролиза расплавленной соли по настоящему изобретению для получения Ti посредством восстановления Са может реализовать получение металлического Ti с высокой эффективностью. Таким образом, способ электролиза расплавленной соли, электролитическая ячейка и способ производства Ti, каждый, по настоящему изобретению могут эффективно использоваться при производстве Ti посредством восстановления Са.The present invention provides a molten salt electrolysis method that can increase the concentration of the metal mist-forming metal in the molten salt by performing electrolysis, provided that the molten salt containing the chloride of the metal mist-producing metal is supplied from one end of the electrolytic cell to the space between the anode and the cathode continuously. or intermittently to provide a flow rate in one direction for the molten salt near the cathode surface and thus to allow the molten salt to flow in one direction near the cathode surface. According to the present invention, while a high current efficiency is maintained, only a molten salt enriched in a metal mist-forming metal such as Ca can be efficiently withdrawn. In addition, this method can be easily carried out by using the electrolytic cell of the present invention. In addition, the application of the molten salt electrolysis method of the present invention to produce Ti by Ca reduction can realize the production of Ti metal with high efficiency. Thus, the molten salt electrolysis method, the electrolytic cell, and the Ti production method each of the present invention can be effectively used in Ti production by Ca reduction.
