Preparation and Characterization of Spherical Fine Nickel Particles by Ultrasonic Spray Pyrolysis

Article Preview

Abstract:

Spherical fine Ni particles were prepared by ultrasonic spray pyrolysis, and the effects of starting materials, carrier gas, and pyrolysis temperature on the crystal phase of the fine particles were investigated. When the mist of starting solution was pyrolyzed at 850 °C in a N2 atmosphere, the crystal phase of fine particles obtained from Ni (CH3COO)2·4H2O was in good agreement with that of Ni. Furthermore, the other phases were not observed. The average particle size of the spherical Ni fine particles was 0.45 μm.
