Abstract
Изобретение относится к области порошковой металлургии, в частности к способам получения тонкодисперсного порошка меди путем электролиза неводных растворов. В способе получения медного порошка путем катодного восстановления меди электролиз ведут с применением пластинчатых растворимых анодов, изготовленных из электролитически чистой меди. Катод - стальной цилиндрический стержень. В качестве электролита используют неводную смесь тригидрата нитрата меди(II) и диметилсульфоксида, состава (моль/л): Cu(NO)∙3HO - 0,1-0,4; ДМСО - до 1 л. Катодное восстановление ведут при температурах 20-40°C и плотности тока 400-1000 А/м. Предлагаемый способ позволяет эффективно использовать растворимые медные аноды для электрохимического получения мелкодисперсного медного порошка с размером частиц 20-40 мкм.The invention relates to the field of powder metallurgy, in particular to methods for producing fine copper powder by electrolysis of non-aqueous solutions. In the method for producing copper powder by cathodic reduction of copper, electrolysis is carried out using plate-like soluble anodes made of electrolytically pure copper. The cathode is a steel cylindrical rod. The electrolyte used is a non-aqueous mixture of copper (II) nitrate trihydrate and dimethyl sulfoxide, the composition (mol / l): Cu (NO) 3HO - 0.1-0.4; DMSO - up to 1 l. Cathodic reduction is carried out at temperatures of 20-40 ° C and a current density of 400-1000 A / m. The proposed method allows the efficient use of soluble copper anodes for the electrochemical production of fine copper powder with a particle size of 20-40 microns.
