摘要
本文用X射线荧光光谱基本参数法测定了Y1-xCexBa2Cu3Oy系列样品中的钇铈钡铜含量,然后折算成它们的原子比,测量的结果与ICP的结果接近。为非破坏地测定高温超导体的实际组分进行了一次尝试。
The determination of Y,Ce,Ba and Cu in a series of Y_[1-x]Ce_xBa_2Cu_3O_y samples has been performed using Xray 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.
