Preparation of Nanoparticles of Metallic Nickel with Different Morphology
Abstract: Some anhydrous eutectics composed of nickel chloride and sodium chloride were obtained by chlorinating the mixtures of sodium chloride and row nickel (average particle size 24.6 μm) with different molar ratios at 700°C. The eutectics were smelt and vaporized at 900°C and the vaporized eutectics were reduced by H2 into nickel powders of high purity with different shapes and different particle sizes. When the molar ratio of NaCl/Ni was 4.0, some spherical nanoparticles of nickel with average particle size 97.42 nm were synthesized. When the molar ratio of NaCl/Ni was 2.0, some cubic superfine particles of nickel with average particle size 101.92 nm were synthesized. Without addition of NaCl, some sintered nickel particles of irregular shape were synthesized. The plausible reasons were given to explain above phenomena.
