Particle size effect on the magnetic properties of NiO nanoparticles prepared by a precipitation method

A Facile and Mild Method for Synthesis of Nickel Oxide Nanoparticles in the Presence of Various Surfactants

“…So far, many synthesis methods have been developed for the preparation of NiO nanoparticles [19,20,22,22] . The chemical methods, including the precipitation of Ni 2+ ions with NaOH, NH4HCO3, CO(NH2)2 or NH3 from an aqueous solution are more promising routes because of inexpensive raw materials and simple processing [23,24,25,26] . However, in most of all these methods, calcinations at the minimum temperature of 250°C are needed to get the crystalline NiO.…”

Structural and microwave absorption properties of Ni(1−x)Co(x)Fe2O4 (0.0≤x≤0.5) nanoferrites synthesized via co-precipitation route

“…Nano-phase spinel ferrites have attracted much attention due to their technological importance in different fields, such as microwave devices, high speed digital tapes and disk recording, ferro-fluids, catalysis, and magnetic refrigeration systems [5][6][7], biosensors, recording colour imaging, targeted drug delivery, catalysts, and pigments [8,9]. The interesting and useful magnetic properties of spinel ferrites depend on the choice of cations along with Fe 2+ and Fe 3+ ions and their distribution between tetrahedral (A) and octahedral (B) sites of the spinel lattice [4,[10][11][12].…”

“…Ni-Co ferrites are important electronic materials which are used in electronic devices suited for high-frequency applications in the telecommunication field [12]. These materials are commercially used in high-quality filters, rod antenna radio frequency circuits, transformer cores, read/write heads for high-speed digital tape and operating devices [12,13].…”

Effect of Calcination Time on Structural, Optical and Antimicrobial Properties of Nickel Oxide Nanoparticles

“…Several techniques, such as hydrothermal [10], sol-gel [11], solid-state reaction [12], electrochemistry [13], micro emulsions [14], spray pyrolysis [15,16] and precipitation [17] methods, have been developed to synthesize NiO nanoparticles.…”
