Analysis of the Composition of Nd-Fe-B Magnetic Material by XRF Using Arc-Melting Prepared Reference Materials

A series of Nd-Fe-B reference materials were prepared by arc-melting, and the standard values of various elements in Nd-Fe-B samples were confirmed by ICP-AES in three different laboratories. The reference materials were used to establish calibration curve for XRF for the elements in Nd-Fe-B materials by fundamental parameter method. The results obtained by XRF were consistent with that by ICP-AES, with RSD (n=11) less than 1.5%.
