摘要：

X射线衍射法定量分析α-石英相，采用的标准一直是YB/T 172-2000 。2021年4月1日开始采用修订后标准。通过对标准修订前后的比较可知：当含量≤5.2%，修订前后绝对误差≤0.10；当含量＞5.2%，修订前后的绝对误差＞0.10；而且随着含量越大，绝对误差也越大。修订后标准很好地继承和发展了YB/T 172-2000技术要求，操作性强，准确度高，重复性好，更方便快捷。试样衍射强度值直接代入工作曲线，即可获得分析结果。

Abstract:

The standard for quantitative analysis of α-quartz phase by X-ray diffraction has always been YB/T 172-2000.The revised standard will be adopted on April 1,2021.The comparison of the standard before and after revision shows that when the content is ≤5.2%,the absolute error before and after revision is ≤0.10；When the content is >5.2%,the absolute error before and after revision is >0.10;and the absolute error increases with the increase of the content.The revised standard has well inherited and developed the technical requirements of YB/T 172-2000.It has strong operability,high accuracy,good repeatability,and it is more convenient and fast.The diffraction intensity value of the sample can be directly substituted into the working curve to obtain the analysis results.

Key words: X-ray diffraction, Quantitative analysis, α-quartz, Method comparison
