Preparation of Ultrafine Metal Nickel Particles by Means of Liquid Spraying of Acetate Solution into RF Plasma

Abstract

The present work studied the formation of ultra fine metal particles (UFPs) by feeding a solution of nickel acetate tetrahydrate into RF plasma using a two liquid atomizing spray nozzle. X-ray diffraction and TEM observation revealed that the UFPs produced by this method were isolated spherical metal nickel particles with a narrow particle size distribution. It was shown that the nickel acetate tetrahydrate was a suitable raw material for the production of metal nickel UFPs using liquid spraying method.
