Index Terms: M-type barium ferrite, citrate sol-gel process, nano-powder, preparation, phase analysis, microscopic morphology, sintering.
Abstract: Nano-powder of M-type barium ferrite (BaFe12O19) were prepared by citrate sol-gel process with the starting materials of stoichiometric amounts, such as Ba(NO3)2•6H2O, Fe(NO3)3•9H2O, and citric acid. The phase analysis was characterized by x-ray diffraction (XRD) . The microscopic morphology of the as prepared nano-powder was observed with transmission electron microscope (TEM). The average crystallite size of M-type barium ferrite nano-powder was found to be about 50 nm. The results show that nano-BaFe12O19 powders was obtained by citrate sol-gel process.
