中文摘要:

      采用熔片法制样，建立了X-射线荧光测定锆矿石中锆、硅、铁、钛、铝、钙的分析方法。使用国家一级标准物质与二氧化锆混合配制的混合标准物质，解决了锆矿石标准物质不足的问题。试样:硼酸锂混合熔剂为1:20，在熔样机中熔成玻璃片，采用经验系数法和散射线内标法校正元素间的谱线重叠效应和基体效应，对标准物质和混配的标准样品进行了分析，标准物质测定结果与推荐值一致，相对标准偏差（RSD%）均小于3.6%。方法能满足高含量锆矿石中主、次量元素的测定。

英文摘要:

      Using the welding pool of sampling, an X-ray fluorescence determination method of Zr、Si、Fe、Ti、Al、Ca in the zirconium ore mine is established. The use of the state level standard material mixed with zirconium dioxide to make a blead standard material solve the insufficiency of the standard of zirconium ore. Sample:partial boric acid lithium mixed flux=1: 20 melted into a glass prototype, using the experience coefficient method and internal standard method of scattering line to correct the overlapping effect of the spectral lines of elements and matrix effect, the standard material and mixed standard samples were analyzed, and the resuits of the standard material agreed with the recommended value. The relative standard deviations (RSD %) were less than 3.6%. This method can meet the determination of the major and minor content elements in the high conteat zirconium ore.
