A possible explanation of thisphenomenon is as follows: In NaCl-KCl melts, complex ions of Ti will form, andchemically, the Ti~(2+) complex ions are less stable as compared to the Ti~(3+) complexions. This will lead to comparatively small overpotential in electrodeposition. There-fore, lower average valence is conductive to the formation of rather coarsercrystals. With a view to improving the current efficiency and the quality of Tiin the electrolysis of TiCl_4 by basket cathode, measures which can raise theconcentration of titanium subchlorides as well as lower the average valence, suchas adding Ti to the gas-melt interface in the basket should be adopted. 收稿日期: 1980-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 杨绮琴 刘冠昆 方北龙 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I3/365 [1] #12 [2] Alpert, M.
