发明名称 Electrolytic reduction of metal oxide particles such as titanium dioxide
摘要 A method of removing oxygen from a solid metal, metal compound or semi-metal M1O by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that reaction of oxygen rather than M2 deposition occurs at an electrode surface and that oxygen dissolves in the electrolyte M2Y and wherein, M1O is in the form of a (sintered) granules or is in the form of a powder which is continuously fed into the fused salt. <??>Also disclosed is a method of producing a metal foam comprising the steps of fabricating a foam-like metal oxide preform, removing oxygen from said foam structured metal oxide preform by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that reaction of oxygen rather than M2 deposition occurs at an electrode surface.The method is advantageously applied for the production of titanium from Ti-dioxide. Also disclosed is a method of producing a metal matrix composite and a fiber reinforced metal composite, wherein the metal matrix is formed by electrolytic reduction after preparation of the composite structure. <IMAGE>
