Wavelength dispersive x-ray fluorescence spectrometric analysis of the compositional constituents in blast furnace slag cements

Abstract

In X-ray fluorescence analysis the empirical method is found to produce precise results but there is often uncertainty regarding accuracy. This has been found most in the quantitative analysis of slags and its products. To obtain accurate and reproducible results, the samples should be dissolved and evaporated to get subsequently resolidified sample or fused into glass beads by mixing the sample with Na2B4O7 for the X-ray fluorescence analysis. But all these techniques are time consuming processes. In our present work, the usual double briquetting technique was used with correction constants, both for enhancement and absorption effects. This gives reproducible analysis of SiO2, Al2O3, CaO and MgO within the acceptable limits of accuracy. The technique covers the usual ranges of the constituents in blast furnace slag cements. The development technique was tested by analysing other analysed blast furnace slag cement samples.
