金属氧化物的电化学还原在难熔金属的生产中占有重要地位。传统的电还原路线具有与固体前驱体表面附近的氧化物积聚以及操作电解液进入前驱体内部有关的局限性。流态化阴极工艺提供了一种很有前途的替代品。在WO_3和LiCl-KCl模型体系上演示了这一过程。用循环伏安法和计时电流法研究了这一过程。考察了熔体中颗粒的流态化速度和浓度等工艺条件及其影响。
The electrochemical reduction of metal oxides is important in the production of refractory metals. Conventional electroreduction routes have limitations related to oxide build-up near the surface of solid precursors, as well as operative electrolyte access to the inner parts of the precursors. The fluidised cathode process offers a promising substitute. The process is demonstrated on a WO3 and LiCl-KCl model system. Cyclicvoltammetry and chronoamperometry were used to investigate the process. Process conditions such as fluidisation rate and concentration of particles in the melt, and their effects, are investigated.
