The Use of Digital Techniques to Aid in the Phase Analysis of Multicomponent Mixtures by X-Ray Diffraction
X-ray diffraction is the most powerful tool available for the determination of the phase composition of multicomponent crystalline mixtures. In order to take advantage of the great potential of digital computers for aiding quantitative X-ray diffraction analysis (QXDA), equipment has been set up to obtain X-ray diffraction data directly in digital form on punched paper tape. The method of using a computer to produce a quantitative analysis from the recorded data is described and results obtained for the analysis of Portland cements are used as an illustration.
