Role of fuels on intrinsic and extrinsic properties of CoFe2O4 synthesized by combustion method

Abstract We have investigated the role of two different fuels viz. glycine and hexamethylenetetramine (HMT) on the electric and magnetic properties of cobalt ferrite synthesized by combustion method. X-ray diffraction study confirms the proper phase formation and spinel structure. Scanning electron microscope study of S 1 (sample prepared by HMT) shows the porous microstructure while that of S 2 (sample prepared by glycine) shows the dense microstructure. The DC resistivity of S 1 is found to be larger than S 2 . The dielectric properties of S 1 and S 2 reveal the usual dielectric dispersion nature. The static contact angle measurement reveals the superhydrophobic and hydrophobic nature for S 1 and S 2 respectively.
