Morphology and crystal-chemical characteristics of cobalt and nickel nanopowders prepared by thermochemical and electrolytic methods

Abstract

The phase composition and morphology of cobalt and nickel powders and nickel foam have been studied by X-ray diffraction and scanning electron microscopy. The cobalt and nickel powders prepared through solution electrolysis are shown to have a dendritic microstructure. The particle morphology of the nanostructured cobalt and nickel powders and nanostructured nickel foam can be described by a three-level (according to the particle size) model.
