Formation, structure, composition in the dispersed state, and behavior of nanoparticles heated in the Mg(OH)$_2$ – Ni(OH)$_2$ system

The effect of nickel content in Mg$_{1-x}$Ni$_{x}$(OH)$_{2}$ nanoparticles produced by reverse co-precipitation on their structural characteristics, morphology and size parameters of crystallites and particles has been studied. The plate-shaped nanoparticles were shown to be predominantly single crystals. It has been determined that when the nickel content $x$ in the hydroxide solid solution is not less than 0.4, the particle size sharply decreases and the number of stacking faults increases. The dependence of the dehydration temperature of Mg$_{1-x}$Ni$_{x}$(OH)$_{2}$ nanoparticles on the nickel content has been revealed.
