[Determination of Fe and Ba in BaFe12O19 samples by binary ratio and X-ray fluorescence spectrometry].

A new quantitative analysis method was established for the determination of Fe and Ba in BaFe12O9 samples by binary ratio and X-ray fluorescence spectrometry. The calibration curve was established by a self-made pure Fe powder(AR) and pure BaCO3 powder(AR) standard sample which was prepared by powder pellet method. The standard sample has the content of Fe 75% and the content of Ba is 17.
