QUANTITATIVE ANALYSIS OF CUBIC AND MONOCLINIC

Abstract The X‐ray diffraction technique presents a simple method for the quantitative analysis of mixtures of polymorphic forms of the same substance The X‐ray spectrometer provides a rapid means for such work In the case of zirconia the relative intensities of the cubic 111 reflection and the monoclinic 111 and 111 reflections are related to the proportions of each form
