Preparation method of silver powder and silver powder

The invention discloses a preparation method of silver powder and the silver powder, relates to the technical field of metal powder, and aims to solve the problems that the silver powder is poor in dispersity, low in tap density and difficult to meet the performance requirements of conductive paste. The method comprises the steps that a silver source solution and a hydrazine hydrate aqueous solution are mixed, a reaction solution is obtained, and the silver source solution contains a silver source substance and an amino protective agent; the reaction liquid is mixed with an organic dispersing agent, silver dispersion liquid is obtained, and the organic dispersing agent contains an alkyl chain; and silver powder is separated from the dispersion liquid. The silver powder is prepared by the preparation method of the silver powder provided by the technical scheme. The preparation method of the silver powder is used for preparing the silver powder. 本公开公开一种银粉的制备方法及银粉，涉及金属粉体技术领域，以解决银粉分散性差、振实密度低，难以满足导电浆料的性能需求的问题。所述方法
