提出一种X射线衍射定量相分析法——μ值法,解决了无法得到待测晶相的标样或一组无非晶相的参考试样时含非晶相待测试样的定量问题。该法测定的结晶度只与待测试样的衍射强度和相的质量吸收系数有关,并采用最小二乘法回归分析,降低误差。
A method of quantitative analysis by X-ray diffraction -μ value method is proposed to solve the problem of the quantitative determination of the sample containing amorphous phase when a standard sample or a group of non-amorphous reference sample can not be obtained. The crystallinity measured by the method is only related to the diffraction intensity of the sample to be tested and the mass absorption coefficient of the phase, and the least square regression analysis is adopted to reduce the error.
