Preparation and Characterization of Spinel Zinc Ferrite ZnFe2O4

Chandrashekhar A. Ladole

Spinel zinc ferrite ZnFe2O4 was prepared by co-precipitation method using the ferric chloride FeCl3.6H2O and zinc chloride ZnCl2 as raw materials and characterized by powder XRD, IR study and TG-DSC analysis. The influence of ferrite synthesis condition, such as Zn/Fe molar ratio, pH value and time was investigated. The results show that the pure spinel ferrite ZnFe2O4 are formed when the Zn/Fe molar ratio as 1 : 2 at pH = 7.5 and product was calcinated at 500oC for 5 hours.
