Hexagonal Magnetoplumbite Compound CaFe12O19 were synthesized by two methods namely Solvo Combustion and Ceramic methods respectively. The compounds were studied by X-ray diffraction technique (XRD), Scanning electron Microscope (SEM), energy dispersive spectroscopy (EDS) and Magnetic Studies. The XRD studies indicate the sample synthesized by Solvo Combustion Method CaFe12O19 doesnot crystallize purely in Magnetoplumbite structure. Its ‘d’ values and (hkl) are slightly different than when small amount of Strontium is added to calcium which crystallize in Hexagonal Structure with a = 5.80 Ǻ and c = 22.15 Ǻ since the ionic radius of Strontium is more than that of Calcium. The SEM images by Solvo Combustion and Ceramic Original Research Article Borkar et al.; AJOPACS, 7(3): 1-7, 2019; Article no.AJOPACS.52310 2 method nearly indicate the morphology of the samples to be Hexagonal structure. The EDS indicates the clear presence of element Ca, Sr, Fe and O in the Solvo combustion and ceramic method prepared sample.
