| Abstract: |
| With certified reference materials of magnesia as calibration samples,a new method was established for the determination of major and minor components including MgO, Al2O3, SiO2, CaO, P2O5 and Fe2O3 in magnesia by X-ray fluorescence spectrometry. The preparation of testing sample and calibration sample were carried out by fusion method. The optimized experimental conditions were obtained as follows: a mixed solution of Li2B4O7-LiBO2(67+33) was used as fusing agent, 1 mL LiBr was used as remover, the fusion temperature was 1 100 ℃, and the fusion time was 20 min. The relative standard deviation (RSD) was less than 3%.The determination results were consistent with the certified values. |
