Abstract：If the ferrovanadium alloy was directly melted in platinum-gold crucible, there were the dangerous for corrosion of platinum-gold crucible. The ferrovanadium sample was firstly digested with HNO3 (1+1) and H2SO4 (1+1). Then sample concentrates was fused in platinum-gold crucible with lithium tetraborate and lithium carbonate by fusion sample preparation method, and the melt was molded in platinum-gold crucible avoiding the corrosion of platinum-gold crucible by sample. After the calibration curve was established with certified reference material of ferrovanadium alloy and the spectral overlapping effect was corrected by the mathematical model in OXSAS software, the accurate determination of V, Al, Si and Mn in ferrovanadium alloy was realized by X-ray fluorescence spectrometry (XRF). The precision test results indicated that the relative standard deviations (RSD, n=9) of testing elements were all lower than 0.7%, which could meet the detection requirements for each element in ferrovanadium alloy. Three certified reference materials of ferrovanadium alloy were analyzed according to the experimental method, and the results were well consistent with the certified values.
