Glass flakes were prepared by melting method. Under the condition of small number of standard samples and incomplete element content, Xray fluorescence spectrometry for simultaneous determination of 12 elements such as Al, Si, Fe, Ca, Mg, P, Ti, Mn, V, Cr, Zr and Nb in rutile was established by using standard samples to artificially prepare synthetic standard samples and adding various standard samples. The lithium tetraboratelithium metaborate mixed flux (67∶33) was used as the melting sample system. The effects of flux selection, melting temperature, dilution ratio and the amount of release agent on the melting effect were discussed. The standard curve was calibrated by the variation theory α coefficient and the spectral line overlap correction, and the relative standard deviation was 0.21%-4.20% (n=10). The results of melting sample preparationXray fluorescence spectrometry were compared with those of volumetric method and inductively coupled plasma atomic emission spectrometry. The results were satisfactory, indicating that this method can be applied to the rapid analysis of major, minor and trace components in rutile.
