Abstract

Способ получения металла электролизом солевого расплава, осуществляемый с заполнением солевым расплавом хлорида кальция электролизной ванны, снабженной анодом и катодом, характеризующийся тем, что любой один электрод из анода и катода устанавливают так, чтобы он окружал другой электрод, катод снабжен по меньшей мере одним сообщающим отверстием, которое обеспечивает сообщение между окруженным катодом внутренним пространством и внешним пространством, и солевому расплаву дают возможность перетекать из одного пространства, внутреннего или внешнего, на снабженной анодом стороне в другое пространство через сообщающее отверстие.A method for producing metal by electrolysis of a molten salt, carried out by filling an electrolysis bath equipped with an anode and a cathode with a molten salt of calcium chloride, characterized in that any one electrode of the anode and cathode is installed so that it surrounds another electrode, the cathode is equipped with at least one communicating hole which provides communication between the cathode-enclosed internal space and the external space, and the molten salt is allowed to flow from one space, internal or external, on the anode-equipped side to the other space through the communication opening.
