An 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 کاملSonochemical assisted synthesis of SrFe12O19 nanoparticles.
We present the synthesis of M-type strontium hexaferrite by sonochemistry and annealing. The effects of the sonication time and thermal energy on the crystal structure and magnetic properties of the obtained powders are presented. Strontium hexagonal ferrite (SrFe12O19) was successfully prepared by the ultrasonic cavitation (sonochemistry) of a complexed polyol solution of metallic acetates and...

متن کاملSynthesis of nickel and cobalt sulfide nanoparticles using a low cost sonochemical method
Nickel and cobalt sulfides are promising materials in different cutting-edge research areas like solar cells, supercapacitors, catalysts, and electrode materials. Nickel and cobalt sulfides with various stoichiometries have been synthesized sonochemically from Ni(CH3COO)2 ∙ 4H2O, Co(CH3COO)2 ∙ 2H2O and different sulfur precursors using a direct immersion ultrasonic probe. The products were char...
متن کاملSynthesis 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...
