With the synthetic standards, valuable metals (Ta2O5, Nb2O5, TiO2, SnO2, and ZrO2) in the tin slags have been determined by the x-ray fluorescence spectrometry. The powder sample and the standards are homogeneously mixed with anhydrous Li2B4O7 and La2O3 in weight ratio of 15 : 42 : 3 respectively. The mixed material is fused at 1,150℃ for 30 minutes to be changed into the glass bead. The bead is ground to (-) 325 mesh size and pelletized. The analytical results obtained in this work are consistent with the data obtained by other common methods within allowable error range. The standard deviation for Ta2O5 in PTS-H sample is 0.12 % at level of 3.40 % content.
