Abstract：The sample was prepared by fusion method. The rapid determination method of aluminum oxide, silicon dioxide, calcium oxide, magnesium oxide, ferric oxide, manganese oxide, chromium oxide, titanium dioxide, nickel oxide and phosphorus pentoxide in stainless steel slag by X-ray fluorescence spectrometry (XRF) was established. The Li2B4O7-LiBO2 (mass ratio of 1∶1) was used as mixed flux. The dilution ratio was 1∶24. The uniform glass sheets of stainless steel slag were prepared by fusion at 1 100 ℃ for 5 min (standing) and 20 min (swing). The series stainless steel slag calibration samples were synthesized with furnace slag standard sample, Cr2O3 high-purity reagent and Ni standard solution. The synthetic samples were determined by XRF to plot the calibration curve. The spectral interference and matrix effect were effectively eliminated by using spectral +overlapping interference coefficient and theoretical alpha coefficient. The stainless steel slag synthetic samples(synthetized by high purity oxides and standard solution) and production samples were analyzed according to the experimental method. The found results were consistent with the reference values or those obtained by wet method. The precision test results indicated that the relative standard deviations (RSD, n=9) were between 0.34% and 9.4%.
