利用固体透氧膜(SOM)法进行了从Ta2O5中提取金属Ta的实验. 在1150℃, 外加直流电解电压3.2 V下,以55.5%MgF2-44.5%CaF2的熔盐体系为介质,阴极为经过预烧成型的Ta2O5, 阳极为氧化锆管内的碳饱和铜液. 测试结果显示: Ta2O5阴极中氧含量大大降低甚至消失, Ta2O5还原为金属Ta.
ABSTRACT In this paper, the method using Solid Oxygen-Ion Membrane (SOM) to produce tantalum from tantalum oxide was investigated. Experiment was carried out at 1150℃ and 3.2V of DC electrolysis potential in the flux system of 55.5wt.%CaF2- 44.5wt.%MgF2. Sintered Ta2O5 solid and liquid copper saturated with carbon loaded in zirconia tube were used as the cathode and the anode, respectively. The results of scanning electron microscopy (SEM) with an energy dispersive X-ray spectrometer (EDX) indicated that the amount of oxygen in tantalum oxide decreased obviously even approached to the zero level and tantalum was produced.
