| Outline of Final Research Achievements |
Electrolytic production of Ti metal and Si metal in molten CaCl2 with their oxides was investigated in this study.
TiO2 dissolved in molten CaCl2 with CaO, and Ti metal electrodeposited. The molar ratio of CaO to TiO2 strongly affected the Ti metal deposition. Ti metal was obtained only in the bath where CaO:TiO2 = 3:2., but the obtained Ti was a little even under this condition. It was suggested that the so-called shuttle reaction hindered the Ti deposition.Calcium silicate dissolved in molten CaCl2, and Si metal was obtained. The influence of the molar ratio of CaO to SiO2 on the Si deposition was seen, but Si metal electrodeposited effectively under the suitable condition.
