Structural Properties of Ba-Zn Hexaferrite Prepared by a Solvent Free Method

Article Preview

Abstract:

The W type barium zinc hexaferrite sample was prepared by a solvent free method with and without presence of cationic surfactant CTAB. The precursors were calcinated at 950°C for 4 hrs in a furnace to obtained BaZn2Fe16O27 crystalline ferrite powder. The effect of proportion of surfactant on structural properties of hexaferrite was studied. The hexaferrite powder was characterized by using various instrumental techniques like XRD and SEM. The structural properties of the samples were investigated by using XRD and SEM. The SEM images of the sample in presence of surfactant shows that surfactant controls the morphology of the particles.
