Rapid analysis of slag and raw materials by XRF

In this paper a rapid analytical method for total iron,CaO,MgO,Al 2O 3,SiO 2,TiO 2,MnO,P 2O 5 in slag or other raw materials by X ray fluorescence spectrometry,along with preparing the specimen of fused glass bead was introduced.Some experimental techniques such as the preparation and the stability of glass bead,the matrix correction method of absorption and enhancement effects were discussed.Calibration curve was carried out with 28 certified reference materials and synthetic standards.The accuracy of the method was verified by the analysis of known reference materials and unknown samples and by the comparison of determined results of this method with those of chemical method or ICP AES method.This method was high quality,rapid, precise, repeatable and practicable.
