Abstract: A method for the determination of Na₂O, MgO, Al₂O₃, SiO₂, P₂O₅, K₂O, CaO, Sc, TiO₂, V₂O₅, Cr₂O₃, MnO, Fe₂O₃, CoO, NiO, CuO, ZnO, Ga, As, Br, Rb, Sr, Y, Zr, Nb, Sn, Sb, Cs, BaO, La, Ce, Nd, Sm, Hf, PbO, Bi and Th in pressed power pellets of ancient ceramics body and glaze by X ray fluorescence spectrometry was reported in this paper. The matrix effect was corrected by experience coefficients, Compton scattering and background as internal standard for trace elements determination. The method has been verified by analyzing the national standard Reference Materials of topsoil and stream sediment and the analytical results were in agreement with the certified values, and RSD (n=11) of most elements (except four elements) are less than 10%, indicating that our method has a high accuracy and can greatly satisfy ancient ceramics research work. The method has been applied to the determination of seven ancient ceramics samples. The obtained results were consistent with the results of other analysis methods.
