| Abstract: |
| In this paper, the contents of Na2O, Al2O3, SiO2, K2O, CaO, Fe2O3 andTiO2 in potassium and sodium feldspar were determined by XRF. Samples were prepared by fusion method. A series of standard solutions for calibration were prepared mainly with the national standards of potassium and sodium feldspar and supplementary with clay, slag and silica standards. The results show that standard deviation of this method is 0.065%~2.9%, which is basically consistent with the standard value. This method, due to its better accuracy, can be used as a routine method for analyzing feldspar-like aluminosilicate minerals and replace the wet chemical analysis method. |
