Morphology of nickel powder contactly precipitated on magnesium in aqueous solutions

Materials Science Aims and scope

Abstract

We analyze the morphology of nickel powders obtained by contact precipitation on magnesium and establish the hierarchy of the shape of particles. We show that in the concentration range of nickel salt of 0.2–2.0 M and at the temperature range 20–95°C, elementary precipitated round particles form rings, arcs, and polygonal conglomerations of the second level of formation. The reproduction of the magnesium surface occurs at the third level. The greater the specific yield of nickel, the better this reproduction. We establish that the value of the specific yield of nickel increases with increase in the temperature and concentration of nickel ions in the solution.
