1 CHARACTERIZATION OF ZINC OXIDE & ALUMINUM FERRITE AND SIMULATION STUDIES OF M-H PLOTS OF COBALT/COBALT-OXIDE Prashant Kumar, Balram S. Yadav, Komal Singh, A.S.Bhattacharyya Centre for Nanotechnology Central University of Jharkhand Ranchi: 8352015 arnab.bhattacharya@cuj.ac.in Zinc oxide was prepared by citrate precursor method [1]. The precursor taken was Zinc acetate dehydrate {(CH 3 COO) 2 Zn.2H 2 O} and this was purchased from Fisher scientific, Citrate acid {C 6 H 8 O 7 } and it was purchased from Fisher scientific, Magnetic stirrer, Magnetic bead , Drying oven, Beakers, Measuring Cylinder. Zinc acetate hydrate aqueous solution was prepared by dissolving 2 g of Zinc acetate in 10 ml of water and likewise Citric acid solution was prepared by dissolving 2 g of Citric acid in 10 ml of water, this solution was taken in de-ionised water. After that the Citric acid solution was added in zinc acetate hydrate solution and the whole solution was then placed onto a magnetic stirrer for two hours. The result was a white precipitate powder and the excess of water was removed from it and was again watched. This Powder was then left for drying at 60◦ for 2h.Finally the prepared sample was calcined in a furnace at 300C for 4 hours. Ultimately we were left with the 2 samples the uncalcined one and the calcined one. Both the sample was then characterized by X-Ray Diffractometry Fig 1: XRD of uncalcined ZnO
