摘要： In a method for reduction of a solid feedstock, such as a solid metal compound, in an electrolytic apparatus a portion of the feedstock is arranged in each of two or more electrolytic cells (50, 60, 70, 80). A molten salt is provided as an electrolyte in each cell. The molten salt is circulated from a molten salt reservoir (10) such that salt flows through each of the cells. Feedstock is reduced in each cell by applying a potential across electrodes in each cell, the potential being sufficient to cause reduction of the feedstock. The invention also provides an apparatus for implementing the method.

摘要： The subject invention pertains to methods for processing a solid material (M1X) comprising a solid solution of a non-metal species (X) in a metal or semi-metal (M1) or a compound between the non-metal species and the metal or semi-metal is immersed in a molten salt (M2Y). A cathodic potential is applied to the material to remove a portion of the non-metal species by electro-deoxidation. To remove the non-metal species at lower concentrations, a source of a reactive metal (M3) is immersed in the molten salt and is electronically connected to the material. Reactions occur at the material, where the non-metal species dissolves in the salt, and at the reactive metal, which reacts with the non-metal species dissolved in the salt to form a reaction product more stable than a compound between the non-metal species and the metal or semi-metal (M1). The non-metal species is thus removed from the solid material.

摘要： A process and apparatus for the synthesis of metal oxide nanopowder from a metal compound vapour is presented. In particular a process and apparatus for the synthesis of TiO2 nanopowder from TiCl4 is disclosed. The metal compound vapour is reacted with an oxidizing gas in electrically induced RF frequency plasma thus forming a metal oxide vapour. The metal oxide vapour is rapidly cooled using a highly turbulent gas quench zone which quickly halts the particle growth process, yielding a substantial reduction in the size of metal oxide particles formed compared with known processes. The metal compound vapour can also react with a doping agent to create a doped metal oxide nanopowder. Additionally, a process and apparatus for the inline synthesis of a coated metal oxide is disclosed wherein the metal oxide particles are coated with a surface agent after being cooled in a highly turbulent gas quench zone.
