Abstract：A method for the fast and simultaneous determination of TiO2, TFe, P2O5, SiO2, Al2O3, MnO, CaO, MgO, ZrO2, Nb2O5, V2O5 in reduced ilmenite samples by X-ray fluorescence spectrometry (XRF) was proposed in this paper. The synthesized standard samples of reduced ilmenite were prepared by spectrum pure reagent, solving the problem of lack in reduced ilmenite standard sample. After the sample was oxidized for 20 min at 850 ℃, it was fused for 16 min at 1 150 ℃ in a high frequency smelting furnace with Li2B4O7 as flux at the mass ratio of 15∶1 to sample and NH4I as releasing agent. It was found that the fuse strip was well-distributed with high strength and good shape. The proposed method was applied to the determination of each component in reduced ilmenite. The results were accordant with the theoretical value, and the relative standard deviations (n=10) of the method were all less than 2.5%, which could meet the determination demand for each component in reduced ilmenite, particularly raising the accuracy for determination of phosphorus.
