Synthesis and Microstructures of Metal Particles Prepared by Spray Pyrolysis

Abstract

Ag, Ni and Cu spherical fine powders were continuously produced by carrying out an aerosol process in a mass nanopowder production apparatus. The particle size, particle morphology, crystal phases and crystallinity of the as-prepared powders were characterized by SEM and XRD. The particles were nonaggregated and they exhibited a spherical morphology with a narrow size distribution.
