Single crystal synthesis of nickel micro-particles with effective involvement of surfactants

[Display omitted] •Single crystal micro-particles of nickel have been prepared using oleylamine as a solvent-reductant system.•A variety of surfactants were also used to observe their effect on nickel micro-particles.•Results showed higher crystallinity of the synthesized micro-particles as compared to standard samples.•Magnetic testing results showed the increase in curie temperature, which was higher than previously recorded. Single-crystal nickel micro-particles have been synthesized using oleylamine which perform both functions, as solvent and as reductant, along with nickel nitrate hexahydrate as the metallic salt and C-TAB as a surfactant. SEM imaging and X-ray techniques were used to confirm the presence of the single-crystal structure of nickel micro-particles. The effect of crystallinity on field-based and especially temperature based magnetic properties resulting in higher curie temperatures of nickel micro-particles was also analyzed. Their morphology and magnetic properties were compared with commercially obtained nickel micro-particles and a variety of other nickel microparticles prepared by using different surfactants in the same system.
