Abstract
1. Способ получения порошков металлов и их сплавов, включающий электрохимическое растворение металлических анодов и осаждение порошка в объеме, в электролите, содержащем химические соединения, способные восстанавливать ионы металлов и регенерироваться на катоде, отличающийся тем, что процесс получения высоко- и нано- дисперсных порошков редких, тугоплавких, благородных и др. d-металлов, например Ni,Fe, Cu, Re, Ti, Nb, Mo, W, Pt, Ag и др., и сплавов, например сталь 12Х18Н10Т, нихром, ВТ-20 и др., ведут в расплаве галогенидов щелочных, щелочноземельных и редкоземельных металлов, окислительно-восстановительный потенциал которого изначально задают отрицательнее условного стандартного электродного потенциала получаемого металла на 100-3000 мВ путем введения в расплав или насыщением из паровой фазы от 0 до 1 мол.% металла соли растворителя, например кальция, натрия и т.п. ! 2. Способ по п.1, отличающийся тем, что в качестве расплава берут смесь хлоридов щелочных металлов с дихлоридом цинка. ! 3. Способ по п.1, отличающийся тем, что в качестве анода используют компактный металл и/или пакет из компактного металла (сплава) и/или различных металлов (сплавов). 1. A method of producing powders of metals and their alloys, including electrochemical dissolution of metal anodes and precipitation of the powder in a volume in an electrolyte containing chemical compounds capable of reducing metal ions and regenerated at the cathode, characterized in that the process for producing highly and nano-dispersed powders rare, refractory, noble and other d-metals, for example Ni, Fe, Cu, Re, Ti, Nb, Mo, W, Pt, Ag, etc., and alloys, for example steel 12X18H10T, nichrome, VT-20, etc. ., lead in a melt of alkali, alkaline earth and rare earth halides metals, the redox potential of which is initially set to be more negative than the conventional standard electrode potential of the obtained metal by 100-3000 mV by introducing from the vapor phase from 0 to 1 mol.% metal of a salt of a solvent, for example, calcium, sodium, etc. . ! 2. The method according to claim 1, characterized in that the mixture of alkali metal chlorides with zinc dichloride is taken as the melt. ! 3. The method according to claim 1, characterized in that the compact metal and / or the package of compact metal (alloy) and / or various metals (alloys) are used as the anode.
