MORPHOLOGY OF ULTRAFINE COBALT AND
NICKEL POWDERS

A.S. Kurlov, A.I. Gusev and A.A. Rempel

Abstract

The phase composition, particle size distribution and morphology of cobalt and nickel powders and foam nickel are examined by X-ray diffraction, laser diffraction and scanning electron microscopy methods. Cobalt and nickel powders obtained by electrolysis of solutions are found to have a dendritic structure. It is shown that the morphology and microstructure of particles of nanostructured cobalt and nickel powders and of nanostructured foam nickel can be described with a three-level (according to particle size) model.
