Synthesis and magnetic investigation of cobalt ferrite nanoparticles prepared via a simple chemical precipitation method
In this research cobalt ferrite (CoFe2O4) nano-crystalline powders were prepared by simple chemical precipitation method using cobalt sulfate. The CoFe2O4 nanoparticles were characterized by X-ray diffraction, scanning electron microscopy and Fourier transform infra-red spectroscopy. The crystallite size of CoFe2O4 nanoparticles was calculated by Debye–Scherrer formula. The effect of precursor...
متن کاملAn investigation on synthesis and magnetic properties of nanoparticles of Cobalt Ferrite coated with SiO2
SiO2-coated Cobalt Ferrite (CoFe2O4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of CoFe2O4 nanoparticles in co-precipitation. The effects of SiO2coating on the magnetic properties of CoFe2O4 nanoparticles were investigated. The structural, morphological and magne...

متن کاملPhysical and magnetic properties of highly aluminum doped strontium ferrite nanoparticles prepared by auto-combustion route
Highly Al3þ ion doped nanocrystalline SrFe12 xAlxO19 (0rxr12), were prepared by the auto-combustion method and heat treated in air at 1100 1C for 12 h. The phase identification of the powders performed using x-ray diffraction show presence of high-purity hexaferrite phase and absence of any secondary phases. With Al3þ doping, the lattice parameters decrease due to smaller Al3þ ion replacing Fe3...
متن کاملSalt-assisted combustion synthesis of cobalt ferrite nanoparticles; magnetic properties and cation distribution measurement by XRD analysis
Current study represents the effect of the size and synthesis method on the cation distribution of cobalt ferrite nanoparticles and on the magnetic properties. The nanoferrites have been synthesized through sol-gel auto-combustion method using metal nitrates as precursor and citrate as fuel. In order to obtain the fine and agglomerated-free particles, we have used salt-assisted combustion react...
