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

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.
