X 射线粉晶衍射仪用高岭石矿物标样研制方法 迟广成，张泉，赵爱林，钟辉 （沈阳地质矿产研究所，辽宁沈阳 110032） 摘要：利用高纯高岭石与刚玉和萤石配制质量分数已知的高岭石标样，选择合适的X 射线粉晶衍射定量测试高岭石的实验条件，采用内标定量方法，作定量分析工作曲线，在完 成高岭石矿石样品的矿物组成及相对含量测试、均匀性检验、稳定性和粒度分布特征检查的 基础上，对低、中、高 3 种不同含量的高岭石样品进行初值测试，结合外委 8 家单位测试结 果，低、中、高 3 种不同含量的高岭石样品最终定值分别为 51.6%、79.5%和 94.1%。资料查 新表明：所取得的高岭石矿物标样定值数据符合现有的行业标准，填补了国内空白；所采用 的定量测试方法与测试条件完全能够被高岭石矿开采企业和研究测试单位所接受，项目完成 了X 射线粉晶衍射仪用高岭石矿物标样研制的要求。 关键词：高岭石标样；内标法；定值测试；X 射线衍射 中图分类号： 文献标识码： X-ray powder diffraction using kaolinite mineral the prototype development method CHI Guang-cheng,ZHANG Quan,ZHAO Ai-lin, ZHONG Hui (Shenyang Institute of Geology and Mineral Resources, Shenyang 110032,China) Abstract: Using high purity montmorillonite and corundum and the mass fraction of kaolinite known the prototype fluorite, choose suitable X-ray powder diffraction quantitative test of kaolinite experimental conditions, using internal standard quantitative method, a quantitative analysis of the working curve, at the completion of the mineral composition and relative content of kaolinite ore sample testing, uniformity, stability, and particle size distribution to check, on the basis of the high, medium and low three different content of kaolinite sample preliminary test, test results combined with external committee eight units, high, medium and low three different content of kaolinite sample finally fixed value were 51.6%, 79.5% and 94.1%, respectively. Data testing show that the kaolinite mineral sample fixed value data obtained in accordance with the existing industry standards, to fill the domestic blank; Adopted by the quantitative test method and test conditions can be completely kaolinite ore mining enterprises and research test units, the project completed the X-ray powder diffraction developed using kaolinite mineral sample request.
