本文在扩充的Rasberry-Heinrich校正方程的基础上,采用Delta系数法对元素间的吸收-增强效应进行数学校正,结合硼砂-硼酸锂制样技术,给出了锆钛酸铅压电陶瓷的X射线荧光分析法.分析未知试样时,只需一只参考标样,且其适用范围较广.同时本方法对相互作用系数准确性的依赖程度也较小.由自编程序用计算机计算相互作用系数和试样组分.当试样组分为PbO64％,ZrO_225％,TiO_27％,La_2O_34％时,本方法的绝对标准偏差分别为0.12％,0.08％,0.04％和0.04％.
Based on the extended Rasberry-Heinrich equation, the Delta coefficient method is used to perform mathematical correction on the absorption-enhancement effect between elements. Combined with the borax-lithium borate preparation technique, the X Ray fluorescence analysis.An unknown sample analysis, only a reference standard, and its wider scope of application.At the same time, the accuracy of the interaction coefficient of the method is also less dependent.Compared with each other by the self-programming program When the sample composition is PbO64%, ZrO_225%, TiO_27%, La_2O_34%, the absolute standard deviations of this method are 0.12%, 0.08%, 0.04% and 0.04%, respectively.
