Silver particles and processes for making them

摘要

There is disclosed a silver powder comprising silver particles, each said silver particle comprising silver components 100-500 nm long, 80-100 nm wide, and 80-100 nm thick, assembled on the surface of silver to form a spherically-shaped, open structured particle, wherein the surface of the particle resembles the surface of an orange rind and the d50 particle size is from about 2.5 μm to about 6 μm. Also disclosed is a process for making these silver particles. The silver particles formed are particularly useful in electronic applications.
