| Abstract: | The national standard sample and the high purity material are selected to prepare the standard sample, and the mixed flux (67%Li2B4O7+33%LiBO2) is used to melt the sample. The contents of SiO2, Fe2O3, MgO, CaO, K2O, TiO2, P2O5, Na, F and Al in sodium cryolite were determined by X-ray fluorescence spectrometer. The test results show that the relative standard deviation (RSD) of each component is between 0.57% and 6.52%. The comparison with the third-party laboratory also shows that this method can meet the requirements of factory detection. |
