WebXRD: Crystallinity, Crystallite Size, AND Texture Analysis (All 3) Default Image X-ray Diffraction (XRD) is a nondestructive analytical technique which can be used to measure both physical and chemical properties of …
WebXRD is one of the most widely used techniques to characterize MNMs. Information such as phase nature, crystal structure, lattice parameters, and crystal grain size can be obtained from XRD data [1–5]. The crystal grain size is estimated by the Scherrer equation using the width of the most extensive XRD peak for a particular sample. Webpowder samples with particle size distribution (PSD), the crystallite size L s obtained from SE, Eq. (1), corresponds to the average value of the volume-weighted PSD.3{6 In this work, a simple line pro le simulation of X-ray di raction peaks in samples with PSD leads to a di erent understanding. It shows that SE provides L
WebOne basic problematic aspect in x-ray diffraction phase analysis is microabsorption effect which may arise from the size of the crystallite phases. Complication of the problem may intensify in sintered ceramic materials where milling of the samples is not simple. We report the Rietveld x-ray diffraction phase analysis of MgO-a-Al2O3 powder ...
