Synthesis and characterization of ultrafine cobalt ferrites

Synthesis, characterization and influence of calcination temperature on magnetic properties of nanocrystalline spinel Co-ferrite prepared by polymeric precursor method

“…For this reason, various methods have been reported in the literature for the preparation of these nanoscale spinel particles such as ceramic method [11], sol-gel [12], co-precipitation [13], solvent evaporation [14], hydrothermal [15], combustion [16], microemulsion [17] and citrate methods [18]. Many works present the synthesis of spinel ferrites using the conventional ceramic powder preparation process [11], which involves a solid state reaction of mechanically mixed metal oxides at high temperatures.…”

Synthesis, characterization and effect of sintering temperature on magnetic properties of MgNi ferrite prepared by co-precipitation method

“…[1]. Various methods such as ceramic method [2], sol-gel method [3], solvent evaporation method [4], hydrothermal method [5], citrate method [6] and combustion method [7] are used for preparation of spinel ferrites. The co-precipitation method is widely used for preparation of ferrites due to its overriding advantages such as composition flexibility.…”
