| titleOfInvention | Method for preparing copper powders |
| abstract | The invention relates to the field of powder metallurgy, in particular, to methods for producing copper powders from solid metal compounds. The purpose of the invention is to increase the specific surface of the obtained powders, increase productivity and reduce the energy intensity of the process. Glycerin, preheated to 135 - 155 ° C, is mixed with copper formate with a mass ratio of copper formate and glycerin equal to 1: (6 - 8), the mixture is heated to 185 ° C and held for 25 minutes. The resulting powder is separated from the reaction medium and washed with alcohol. The method allows, while maintaining a high degree of dispersion of copper powders, to increase the specific surface area by 1.7 - 2.0 times, and the process productivity - by 1.6 - 1.8 times. |
