摘要： A solid material (M X) (6) comprising a solid solution of a non-metal species (X) in a metal or semi-metal (M ) or a compound between the non-metal species and the metal or semi-metal is immersed in a molten salt (M Y) (4). A cathodic potential is applied to the material to remove a portion of the non-metal species by electro-deoxidation. As this reaction proceeds it becomes less efficient and so to remove the non-metal species at lower concentrations a source of a reactive metal (M ) (8) is immersed in the molten salt and is electronically connected to the material, either by electronic conduction through the salt or through an external circuit. 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 (M ). The non-metal species is thus removed from the solid material.

摘要： A process for producing a high-purity metallic Ti or Ti alloy, comprising, while retaining a molten salt containing CaCl2 and having Ca fused therein in reaction vessel (1), electrolyzing the molten salt of the reaction vessel and feeding a metal chloride containing TiCl4 into the molten salt so as to react with any Ca generated on the negative electrode side by the electrolysis to thereby produce granular Ti or Ti alloy in the molten salt. Further, when the reaction vessel is fitted with diaphragm (4) adapted to, while permitting circulation of the molten salt in the reaction vessel, partition the interior of the reaction vessel into the positive electrode (2) side and the negative electrode (3) side and block the transfer of Ca formed on the negative electrode side of the reaction vessel to the positive electrode side, any back reaction by Ca can be effectively suppressed. Still further, when a conductive porous material is used as the negative electrode, enhanced productivity can be realized.

摘要： An alkali metal generating agent (1) for use in forming a photoelectric surface emitting a photoelectron corresponding to an incident light or a secondary electron emission surface emitting a secondary electron corresponding to an incident electron, which comprises an oxidizing agent comprising at least one vanadate having an alkali metal ion as a counter cation and a reducing agent for reducing the above cation. The above metal generating agent (1), which includes a vanadate having weaker oxidizing power than that of a chromate, undergoes slower oxidation-reduction reaction, which results in easier reaction rate control as compared to a conventional technique using a chromate, leading to the generation of an alkali metal with good stability.

摘要： The present invention relates to a method for producing a metal by a direct oxide reduction process with Ca. A CaCl 2 -based molten salt containing Ca is held in a reduction chamber 1, a metal oxide is introduced into the molten salt in the reduction chamber 1, and the metal oxide is reduced with the Ca in the molten salt to form said metal. The metal formed in the molten salt is separated from the molten salt in a separation means 2, and the molten salt deprived of the metal is introduced into a chlorination chamber 7 and subjected to chlorination treatment with chlorine gas to eliminate the byproduct CaO in the molten salt. The molten salt after chlorination treatment is introduced into an electrolysis chamber 8 and electrolyzed for the formation of Ca and chlorine from CaCl 2 , and the thus-formed Ca or Ca-containing molten salt is transferred from the electrolysis chamber 8 to the reduction chamber 1. The chlorine obtained in the electrolysis chamber 8 is used in the chlorination chamber 7. Thus, the present invention provides a metal production method and an apparatus wherein high levels of productivity are obtained and the product metal can be inhibited from carbon contamination due to CaO, without any generation of CO 2 from the production process, while their being based on the direct oxide reduction process comprising the step of reducing a metal oxide with Ca.
