| Abstract: | The determination of Y, Ce, Ba and Cu in a series of Y(1-x)Ce(x)Ba(2)Cu(3)O(y) samples has been performed using X-ray fluorescence fundamental parameter method. The composition is given in atomic percentage. The results agree well with those obtained by ICP. It is shown that this method is appropriate for the determination of compositions of the high temperature superconductors. In addition, the influence of oxygen on analytical elements has been discussed in this paper. The fraction of the matrix total mass absorption that is associated with oxygen for each analytical line can not be larger than 3.44%. The determined composition of the samples show different from their nominal composition,which may affect the properties of high temperature superconductor. |
