简介：CaTiO3的形成行为在钛铁矿的electro-deoxidization期间专注准备FeTi合金被实验和模拟调查。结果显示中间的产品的形成和分解，CaTiO3,在钛铁矿的electro-deoxidization期间是不可避免的步专注。CaTiO3能在电气化学的过程期间通过熔融的盐和电气化学反应的hydrolyzation被产生。为CaTiO3的产生的主要原因在阴极是在从熔融的盐和TiO2的Ca2+之间的电气化学反应。与electro-deoxidization继续，CaTiO3是进一步的electrolyzed形成钛低值氧化物。当在由在sintering期间增加CaCO3的阴极的CaTiO3形式处理时，当前的效率能被改进。
