Abstract

Foreliggende oppfinnelse tilveiebringer en fremgangsmåte for å elektrolysere saltsmelte som kan forhøye konsentrasjonen av metalldannende metalltåke i saltsmelten ved å utføre elektrolysen under betingelser ved at saltsmelten inneholdende klorid av metalldannende metalltåke blir tilført fra én ende av en elektrolysecellen til et mellomrom mellom en anode og en katode på en kontinuerlig eller intermitterende måte for å tilveiebringe en strømningshastighet i én retning til saltsmelten i nærheten av overflaten av katoden og således for å tillate saltsmelten å strømme i én retning i nærheten av overflaten av katoden. I henhold til foreliggende oppfinnelse, mens høyt strømutbytte opprettholdes, kan bare saltsmelten anriket med metalldannende metalltåke slik som Ca tas ut effektivt. Videre kan denne fremgangsmåte lett utføres ved anvendelse av elektrolysecellen i henhold til foreliggende oppfinnelse. Videre kan anvendelse av fremgangsmåten for å elektrolysere saltsmelte i henhold til foreliggende oppfinnelse til fremstilling av Ti ved reduksjon av Ca realisere fremstillingen av metallisk Ti med høy effektivitet. Således, fremgangsmåten for å elektrolysere saltsmelte, elektrolysecellen, og fremgangsmåten for å produsere Ti, hver i henhold til foreliggende oppfinnelse, kan effektivt bli anvendt i fremstillingen av Ti ved reduksjon av Ca.BACKGROUND OF THE INVENTION The present invention provides a method of electrolyzing salt melts which can increase the concentration of metal forming metal mist in the salt melt by conducting the electrolysis under conditions that the salt melt containing chloride of metal forming metal mist is fed from one end of an electrolytic cell to a space between an anode and a cathode. a continuous or intermittent means for providing a flow velocity in one direction to the salt melt near the surface of the cathode and thus to allow the salt melt to flow in one direction near the surface of the cathode. According to the present invention, while maintaining high current yield, only the salt melt enriched with metal-forming metal mist such as Ca is efficiently removed. Furthermore, this method can be easily carried out using the electrolysis cell of the present invention. Furthermore, the use of the process of electrolyzing salt melts according to the present invention for the preparation of Ti by reducing Ca can realize the production of metallic Ti with high efficiency. Thus, the process of electrolyzing the salt melt, the electrolysis cell, and the process of producing Ti, each according to the present invention, can be effectively used in the preparation of Ti by reducing Ca.
