【摘要】 根据四氯化钛熔盐电解法的研究现状,本文选择低熔点的47.5％LiCl-37.5％KCl-15％NaCl（摩尔％）系作电解质。为了探讨此体系的优越性和采用它的可行性,对盐系中反应Ti（固）+2TiCl₃（熔）=3TiCl₂（熔）的平衡进行了研究,在此基础上采用60～130安培电解槽,在550～640℃的温度范围内,进行了四氯化钛电解探索性试验,将所获得的指标5等克分子NaCl-KCl系为电解质的电解结果进行了对比考察,证明采用三元系可进行低温电解,在400℃不敞开出炉,并可大幅度地降低金属钛中的含铁量。更多还原

【Abstract】 According to the present state of the study on the electrolysis of TiCl₄, the 47.5％ LiGl-37.5％ KCl-15％ NaCl（mole percent） system was chosed as the electrolyte. In order to investigate its advantages and feasibility, the equilibrium between metallic titanium and low valent titanium was studied. On this basis, the electrolysis of TICl₄ are carried out at 550～640℃ by using the cell with scale of 60～130 ampers. The obtained deta was compared with that of the electrolysis with the equi-molar NaCl-KCl system. Experiments show that the trinary system can be used for low temperate electrolysis, which permits the product to be taken out of the cell at temperatures≤400℃ in the open atmosphere and considerably decreases the content of iron in metallic titanium.更多还原
