Liquid phase preparation method of nanoscale superfine copper powder
ActiveCN119407190ALarge particle sizeNarrow particle size distributionTransportation and packagingMetal-working apparatusFluid phaseMetallurgy
The invention belongs to the technical field of nano materials, and particularly relates to a liquid-phase preparation method of nanoscale superfine copper powder. The nucleation growth process of the copper powder is controlled by adding a reducing agent in a segmented mode, a certain amount of dispersing agent is added in the reduction process to guarantee good dispersion of copper powder particles in a liquid phase, the situation that the nucleation number of the copper powder is reduced and the particle size is increased due to agglomeration of the copper powder in the liquid phase nucleation process is avoided, and the large-size copper powder is continuously dissolved and then separated out through reduction in each segment. And the particle size distribution is further optimized, and finally the nanoscale superfine copper powder which is good in dispersion, narrow in particle size distribution range and good in circularity is obtained.
