| Abstract: | The contents of fluorine, calcium and silicon dioxide in fluorite were determined by X-ray fluorescence spectrometry. Samples were treated with a mixed flux (LiBO2: Li2B4O7: sample=1: 2: l. 2). Accurate quantitative results were obtained. The maximum absolute error for F determination between this method and chemical analysis method in the range of 77%~98% CaF2 is 0. 6%. Results show that this method can meet the requirement for routine analysis of fluorite. |
