采用偏硼酸锂和四硼酸锂混合熔剂熔融法制样，波长色散X射线荧光光谱法测定重晶石中钡、锶、铁、铝、硅。采用理论α系数和经验系数相结合的方法校正元素间的基体效应。测定重晶石试样各组分的相对标准偏差(RSD，n=12)均小于5.5%，结果与化学分析法吻合。

A method has been developed for direct determination of Ba, Sr, Fe, Al and Si elements in baryte samples using fusion method by Axios PW4400 XRF spectrometer. The matrix effect was corrected by theoretical alpha coefficients and empirical coefficients. The precision (RSD, n=12) of the method is less than 5.5%for major elements and other elements.
