【Abstract】 The sample pellets of limestone were prepared by edging and underlaying pellets with boric acid. The contents of SiO 2, CaO and MgO in limestone were determined by wavelength dispersive X-ray fluorescence spectrometry. It is shown that this method has good accuracy and precision and the results are comparable to those obtained by chemical analysis.更多还原
