Abstract
Представлен способ получения металла или сплава из металлсодержащего материала удалением O, S или N из твердого тела металлсодержащего материала электролизом в электролитическом элементе. Электролитический элемент содержит расплавленную галогенидную соль или смесь галогенидных солей в качестве электролита. Катион соли выбран из группы, включающей Ca, Ba, Li, Na, K, Mg, Sr, Cs и Y. В одном аспекте изобретения способ включает проведение электролиза при условиях, в которых твердое тело металлсодержащего материала составляет часть катода электролитического элемента, причем катод включает проводник для электрического соединения катода с электрическим потенциалом, при этом проводник имеет высокое сопротивление химической коррозии, вызываемой электролитом при высоких температурах, и проводник, по меньшей мере, частично погружен в электролит. В другом аспекте изобретения способ включает проведение электролиза при условиях, в которых потенциал, наложенный между анодом и катодом электролитического элемента, выбран таким образом, чтобы избежать постоянного разложения электролита до такой степени, при которой предотвращается существенное осаждение катиона электролита на катоде и, по существу, предотвращается перенос материала анода в направлении катода и на катод. Раскрыт также катод, предназначенный для использования в способе. Катод включает тело из металлсодержащего материала, распределенного вокруг одного или нескольких электрических проводников, которые являются, по существу, инертными в электролите при высоких температурах и которые обеспечивают множество восстановительных зон на катоде.Международная заявка была опубликованаA method is presented for producing a metal or alloy from a metal-containing material by removing O, S or N from a solid of a metal-containing material by electrolysis in an electrolytic cell. The electrolytic cell contains molten halide salt or a mixture of halide salts as an electrolyte. The salt cation is selected from the group comprising Ca, Ba, Li, Na, K, Mg, Sr, Cs and Y. In one aspect of the invention, the method includes electrolysis under conditions in which the solid body of the metal-containing material forms part of the cathode of an electrolytic cell, includes a conductor for electrically connecting the cathode to an electrical potential, while the conductor has high resistance to chemical corrosion caused by electrolyte at high temperatures, and the conductor is at least partially immersed in the electrolyte. In another aspect of the invention, the method includes conducting electrolysis under conditions in which the potential imposed between the anode and the cathode of the electrolytic cell is chosen so as to avoid permanent electrolyte decomposition to such an extent that substantial electrolyte cation deposition on the cathode is prevented and, in essence, prevents the transfer of anode material in the direction of the cathode and on the cathode. Also disclosed is a cathode for use in the method. The cathode includes a body of metal-containing material distributed around one or more electrical conductors that are essentially inert in the electrolyte at high temperatures and which provide many reducing zones at the cathode. The international application has been published
