Abstract: | A processes of formation of nanostructured powders of nickel oxide by annealing in the temperature range of 200–700°C of the
nickel hydroxide obtained by the sol-gel method at 80°C from solutions of nickel nitrate by precipitation with alkali in the
presence of surfactant AF-12 (polyethylene oxide alkylphenyl ether) was investigated. The formation of nanostructured powders
of nickel oxide in the presence of a surfactant reduces the size of nanoparticles to 20–25 nm, which is 1.5 times smaller
than the particles obtained without a surfactant. The effective influence of surfactant on the particle size begins in the
temperature range of its decomposition and evaporation equal 350–400°C. |
