X射线衍射物相定量分析内标法标准曲线库的建立

Development and Application of a Standard Curve Database in Quantitative Phase Analysis by XRD Based on the Internal Standard Method

摘要: 在Rigaku D／Max-2200型X射线衍射仪（XRD）定量分析软件的基础上，制作了无机非金属材料中常用的SiO2（石英）、Al2O3（刚玉）、TiO2等9种组分用XRD采用内标法进行物相定量分析时的标准曲线。结果表明，这些标准曲线的可信度R在0．928～0.980。通过对已知含量样品的测量，分析结果与实际值一致，说明建立的标准曲线完全可用于高精度物相定量分析。
