Abstract:
      This study demonstrated a novel analytical approach to determine concentration of Fe, Sr and Si elements in semi-finished products of permanent magnetic ferrite by X-ray fluorescence measurement. Samples were melted with bead and mixed melting reagents. Self-made synthetic standards were used for quantification analysis. Our results indicated that the minimum relative standard deviation of 0.1% could be achieved for the eleven parallel measurements, indicating high accuracy and good reproducibility for the analytical approach we developed and demonstrated in this study. It concluded that when analyzing real samples by XRF, the results were consistent with that of traditional chemical analysis methods.
