Abstract：The samples were prepared by fusion method using anhydrous lithium tetraborate as flux. The determination method of seven components (including MoO3, Pb, Cu, SiO2, CaO, Fe2O3 and K2O) in molybdenum trioxide by X ray fluorescence spectrometry (XRF) was established. The instrumental parameters, analytical lines and curve fitting were studied using Mo as the main analytical element. Moreover, some factors in sample preparation by fusion method (such as the selection of flux, releasing agent, fusion temperature and fusion time) were detailedly discussed. The samples which had been analyzed by chemical method for several times were used as calibration samples to plot standard curve.The corresponding correction programs were selected for correction. The proposed method was applied to the analysis of molybdenum trioxide samples, and the results were in good agreement with those obtained by wet method. This method could meet the determination requirements of seven components in molybdenum trioxide samples.
