Abstract

En fremgangsmåte for å fremstille Ti, omfattende en reduksjonstrinn for omsetning av TiCl4 med Ca i en CaCl2-inneholdende saltsmelte som har Ca oppløst deri for derved å danne Ti partikler, et separasjonstrinn for separering av Ti partikler dannet i nevnte saltsmelte fra nevnte saltsmelte, og et elektrolysetrinn for elektrolyse av saltsmelten for å øke Ca konsentrasjonen, hvori saltsmelten med øket Ca-konsentrasjon i elektrolysetrinnet blir tilført til en reguleringscelle for derved å gjøre Ca konsentrasjon konstant i saltsmelten og deretter blir saltsmelten anvendt for reduksjon av TiCl4 i reduksjonstrinnet. I foreliggende oppfinnelse kan Ca-konsentrasjonen i saltsmelten som skal bli tilføres til den tilsvarende reduksjonsbeholderen, bli hemmet fra fluktuerende og, samtidig, opprettholde høye konsentrasjonsnivåer. Videre kan et stort volum av saltsmelten behandles kontinuerlig. Derfor kan reduksjonsomsetningen av TiCl4 bli effektivt utført og fremgangsmåten kan bli effektivt anvendt ved fremstilling av Ti ved Ca reduksjon som en produksjonsprosess for å realisere Ti produksjon i en industriell skala.A process for preparing Ti, comprising a reduction step for reacting TiCl4 with Ca in a CaCl2-containing salt melt having Ca dissolved therein to form Ti particles, a separation step for separating Ti particles formed in said salt melt from said salt melt, and an electrolysis step for electrolysis of the salt melt to increase the Ca concentration, wherein the salt melt with increased Ca concentration in the electrolysis step is supplied to a control cell thereby rendering Ca concentration constant in the salt melt and then the salt melt is used to reduce TiCl4 in the reduction step. In the present invention, the Ca concentration in the salt melt to be supplied to the corresponding reduction vessel can be inhibited from fluctuating and, at the same time, maintaining high concentration levels. Furthermore, a large volume of the salt melt can be treated continuously. Therefore, the reduction reaction of TiCl4 can be effectively carried out and the process can be effectively used in the preparation of Ti by Ca reduction as a production process to realize Ti production on an industrial scale.
