Title:
METHOD FOR ELECTROLYSIS OF MOLTEN SALT, ELECTROLYTIC CELL, AND PROCESS FOR PRODUCING Ti USING SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2007/026565
Kind Code:
A1
Abstract:
This invention provides a method for the electrolysis of a molten salt that can
enhance metal fog formation metal concentration of the molten salt. In the method,
electrolysis is carried out in such a state that a molten metal containing a chloride
of a metal fog forming metal is supplied from one end of an electrolytic cell to
a part between an anode and a cathode in a continuous or intermittent manner to
provide a flow rate in one direction to the molten salt in its part near the surface
of the cathode and thus to allow the molten salt to flow in one direction at the part
near the surface of the cathode. In the method, while high current efficiency
is maintained, only a molten salt enriched with a metal fog forming metal such
as Ca can be effectively taken out. Further, this method can easily be carried
out by the electrolytic cell according to the present invention. Furthermore,
the application of the method for the electrolysis of a molten salt to the production
of Ti by Ca reduction can realize the production of metal Ti with high efficiency.
Thus, the method for the electrolysis of a molten salt, the electrolytic cell,
and the process for producing Ti can be effectively utilized by the production
of Ti by Ca reduction.
