Quantitative phase analysis
The intensities of the peaks in a powder diffraction pattern are shown to scale with the mass of contributing material. Thus, for a sample comprising several phases, the mass fractions of the different phases can be obtained, at least in principle, from the ratios of intensities of peaks from different phases. Individual peak methods, such as the polymorph method, are described. There is a particularly simple connection between the mass of a phase and the corresponding scale factor as obtained in a multiphase Rietveld method analysis, and this is finding increasing application in quantitative phase analysis. The relative merits of X-rays and neutrons for phase analysis, analysis with or without standards, and the estimation of errors, are discussed. Applications to magnesia-partially stabilised zirconia (Mg-PSZ) and studies of the synthesis in situ of Ti3SiC2 are described in detail.
