A UNIVERSAL METHOD FOR X-RAY QUANTITATIVE PHASE ANALYSIS WITHOUT STANDARD
普适X射线无标定量相分析方法

Based on the works of Zevin and Guo, a quantitative phase analysismethod without standard has been developed. Calculation of absorption coefficientof the sample and addition of extra phase are not necessary. In spite of the num-ber of phases in the sample, only the interesting phases are analysed. The composi-tion is expressed by diffraction intensities from different phases in the same sam-ple, thus, errors caused by the difference between different samples and experimen-tal conditions will be avoided.
