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

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 S₁ (sample prepared by HMT) shows the porous microstructure while that of S₂ (sample prepared by glycine) shows the dense microstructure. The DC resistivity of S₁ is found to be larger than S₂. The dielectric properties of S₁ and S₂ reveal the usual dielectric dispersion nature. The static contact angle measurement reveals the superhydrophobic and hydrophobic nature for S₁ and S₂ respectively.
