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。
Based on the quantitative analysis software attached in Rigaku D/Max-2200 X-ray diffractometer, a standard curve database for quantitative phase analysis by XRD with internal standard method for 9 inorganic compounds including quartz, corundum, TiO2, etc. was developed. The reliability of the standard curve database has been validated by the quantitative phase analysis of samples with assigned values. The results are in good agreement with due values with reliability of 0.928 - 0.980, which indicates that the database is suitable for the high-precision XRD quantitative phase analysis.
