摘要
采用熔盐电解法,在700℃的NaCl-CaCl_2熔盐体系中直接电解固态金属氧化物制备钛铁合金化合物,以固态Fe粉和TiO_2粉混合物为阴极,石墨棒为阳极,刚玉坩埚电解槽,槽电压3.4 V.结果表明,Fe粉和TiO_2粉被电解得到钛铁合金.本文对Fe和TiO_2不同配比阴极进行了研究,发现不同铁含量的阴极产物不同,在前7 h内随着铁元素含量的增加电解反应速度提高.
The Ti-Fe alloy compound was prepared by FFC in the molten salts at 700℃. The preformed cathode feed was fabricated with the slurry of mixing TiO2 and Fe power. The graphite rod was used as the anode in the corundum crucible. At cell voltage of 3.4 V, electro-deoxidation was carried out. With different stoichiometric ratios of Fe and TiO2 powder, different currency-time plots were gotten, which showed that the more Fe addition, the quicker the reaction speed is during the first 7 hours deoxidation.
