Abstract
A silver powder comprising silver particles, each silver particle comprising silver components 100-2000 nm long, 20-100 nm wide and 20-100 nm thick assembled to form a spherically-shaped, open-structured particle, wherein the d50 particle size is from about 2.5 μm to about 6 μm is disclosed. Also disclosed is a process for making these silver particles. The silver particles formed are particularly useful in electronic applications.
