The low O²⁻ diffusion rate in the electro-deoxidation of titanium containing compounds by either the OS process or the FFC process leads to a low reaction speed and a low current efficiency. In this study, Ca₃Ti₂O₇ was used as a precursor to improve the reduction speed of titanium. Because of the greater number of “diffusion channels” created in cathode as Ca²⁺ liberates from Ca₃Ti₂O₇ precursor in the electro-deoxidation process, the O²⁻ diffusion rate was improved significantly by using Ca₃Ti₂O₇ instead of CaTiO₃ as precursor. Parallel constant voltage electrolysis (3.2 V) confirms that Ca₃Ti₂O₇ and CaTiO₃ are reduced simultaneously because of their similar crystal structures. However, the reduction area of Ca₃Ti₂O₇ spreads much faster than that of CaTiO₃, indicating a difference in the O²⁻ diffusion rate. Constant voltage cyclic voltammetry (CV) and theoretical analysis of the crystal structure were also conducted to compare the differences between Ca₃Ti₂O₇ and CaTiO₃. The results indicate that using a precursor with a greater number of soluble cations, titanium reduction speed can be greatly improved in the electro-deoxidation process. Finally, a new electrolysis method for converting and recycling excess CaO from the Ca₃Ti₂O₇ precursor was proposed.

通过OS工艺或FFC工艺对含钛化合物进行电脱氧时，O ^2-扩散速率低，导致反应速度低和电流效率低。在这项研究中，Ca ₃ Ti ₂ O ₇被用作前驱体以提高钛的还原速度。由于在电脱氧过程中，当Ca ²⁺从Ca ₃ Ti ₂ O ₇前驱体释放时，在阴极产生的“扩散通道”数量增加，因此使用Ca ₃ Ti ₂ O _7可以显着提高O ^2-的扩散速率。代替CaTiO ₃作为先驱。平行恒压电解（3.2 V）证实Ca ₃ Ti ₂ O ₇和CaTiO ₃由于它们相似的晶体结构而同时被还原。但是，Ca ₃ Ti ₂ O ₇的还原面积比CaTiO ₃的还原面积扩散快得多，表明O ^2-扩散速率不同。还进行了恒压循环伏安法（CV）和晶体结构的理论分析，以比较Ca ₃ Ti ₂ O ₇和CaTiO ₃之间的差异。。结果表明，使用具有大量可溶性阳离子的前体，可以在电脱氧过程中大大提高钛的还原速度。最后，提出了一种新的电解方法，用于从Ca ₃ Ti ₂ O ₇前体中转化和回收多余的CaO 。
