无机材料中24种组分X射线衍射物相定量分析外标法标准曲线库的建立

在Rigaku D／max-2200型X射线衍射仪定量分析软件的基础上，扩大并制作了外标法对无机材料中石英、刚玉、TiO2、BaTiO3等24种组分进行物相定量分析时的标准曲线，所制作标准曲线的相关系数为0．925～0．999。通过对已知含量样品和部分实际样品的测量，结果与实际值基本相符或和内标法的测量结果基本一致，说明建立的标准曲线可用于物相定量分析。

Foundation of the Standard Curve Database for Quantitative Phase Analysis of 24 Components in Inorganic Materials by X-ray Diffractometry Based on External Standard Method

Based on the quantitative analysis software attached in Rigaku D/max-2200 X-ray diffractometer, the quantitative analysis standard curves of external standard method for phase analysis of 24 components such as quartz, corundum, TiO2, BaTiO3, etc. in inorganic materials, were prepared. Results show that the correlation coefficients of the standard curves are in the range of 0. 925 - 0. 999. The method has been applied to the analysis of reference samples and the results are accorded with the reference values and those provided by the internal standard method. It indicates that the prepared standard curves are suitable for XRD quantitative phase analysis.
