| 摘要 |
Oxygen is removed from metal or metalloid oxides by electrolysis in a fused salt, to produce elements or alloys, so as to prevent problems of cell contamination and poor power efficiency, particularly in scaled up electro-deoxidation processes. Cell current is controlled not to exceed a selected threshold for substantially all of the electrolysis process. The process may include a first constant current phase and a second constant voltage phase.
