Separated nano silver powder (HW-A110) refers to metallic elemental silver with a particle size in the nanometer range, typically ranging from 20nm, 50nm, 80nm, 100nm, and appearing as a solid gray black powder. It is a functional material widely used in various fields such as electronics, chemical engineering, and materials. Its preparation process and quality have a significant impact on the performance of the final product.

The method of preparing silver powder with ultrasound homogenizer assistance involves introducing ultrasound into a reaction vessel and conducting oxidation-reduction reactions under high-speed stirring to generate silver powder. The cavitation effect of ultrasonic homogenizer mixer and the mechanical shear force generated by high-speed stirring of surfactants are utilized to break down a large number of bubbles into smaller bubbles. The presence of a large number of small bubbles can serve as crystal nuclei in the reaction system, which is beneficial for generating smaller silver crystal particles. Under the influence of surface energy, the grains aggregate into porous spherical silver powder. In order to prevent secondary agglomeration of the generated powder, a coating solution is added, and micro nano bubbles are used to form particles with smaller diameters.
