摘要：
The LiI-KI-CsI ternary system has a eutectic point at 204 degrees C. In this study, the electrodeposition of Ti in eutectic LiI-KI-CsI at 300 degrees C and 250 degrees C was investigated. Firstly, the concentration of Ti(2+)in the eutectic molten salt was measured at 300 degrees C under TiI2-saturated condition. We determined the concentration to be 0.18 mol% in cation ratio. After that, electrodeposition of Ti was demonstrated at 300 degrees C and 250 degrees C. The cathode and anode were Mo and Ti, respectively. At both temperatures, metallic Ti was obtained and confirmed by XRD. This result indicates for the first time that a new electrolytic process to produce bulk metal Ti below 300 degrees C is possible.
