摘要： A metal oxide feed material for an electrochemical reduction process is disclosed. The feed material is in the form of powders and/or pellets that have sufficient porosity, typically 35-60%, to enable penetration of molten electrolyte into the powders and/or pellets during the course of an electrochemical reduction process in an electrolytic cell and subsequent washing of electrolyte from the powders and/or pellets after the powders and/or pellets are discharged from the cell. A process for preparing the metal oxide feed material is also disclosed.

摘要： A process for electrochemically reducing metal oxide feed material in a solid state is disclosed. The process includes the steps of agitating an electrolyte and metal oxide powders in the electrolyte and applying an electrical potential across a cathode in contact with the electrolyte and an anode and electrochemically reducing the metal oxides.

摘要： A process for minimising reoxidation of reduced material is disclosed. The process applies to reduced material that has been formed by a process of electrochemically reducing a metal oxide feed material, such as titania, in a solid state in an electrolytic cell containing a molten electrolyte. The process for minimising reoxidation includes applying an electrical potential to reduced material at least while the reduced material remains immersed in the molten electrolyte.

摘要： An electrolytic cell (1) for reducing metal oxide powders and/or pellets in a continuous or semi-continuous manner, the cell includes a cathode (25) in the form of a plate that has an upper surface for supporting metal oxide powders and/or pellets. The plate is supported for movement so as to cause the metal oxide on the upper surface to move toward a forward end of the plate while immersed in a molten electrolyte (21). The cell includes multiple anodes (23) and support structures (63,65) that separately support the cathode and the anodes from above the cell. In a preferred embodiment the anode support structure enables adjustment of the spacing of the anodes above the upper surface of the cathode.
