Production of metal material by composite compound

Abstract

This invention relates to a method of preparing metal material using complex compounds. Electrolysis is carried out in the electrolyte under the protection of inert gas or air containing M3Y with composite compounds of M1M2X combine with the collector as a cathode and carbon, metal or conductive ceramic as anode. Controlling electrolysis voltage, so that M2 reduction reaction is the dominated reaction, and M1 and X is partly or all dissolved in the electrolyte as electrolysis going on. When M1 is H, M1 can be reduced to gas leaving away the cathode. At the end of electrolys, M2 alone or with part of the M1 and X-stay is left on the cathode, which is the corresponding metal. Since M1X part or all leave away cathode in this invention during electrolysis process, the reactivity and ability of cathode is enhanced, the reaction rate and the current efficiency are effectively improved and energy consumption is reduced.

Description

technical field

[0001] The invention relates to a method for preparing metal materials from composite compounds, and belongs to the field of electrometallurgy, new materials and new preparation technologies. Background of the invention

[0002] Metals, semi-metals, alloys, intermetallic compounds and other materials are currently mainly produced and prepared by high-temperature thermal reduction and high-temperature smelting of carbon or metals. This method is used in the smelting of steel, titanium, niobium, tantalum and some alloy materials. Industrial application, but this kind of method has high reaction temperature, high requirements on equipment and devices, and huge energy consumption and serious pollution. With the increasing attention to energy and environmental issues, it is very urgent to develop new technologies with low energy consumption and less pollution .

[0003] Some metals, semi-metals, alloys, intermetallic compounds and other materials can also be prep...
