The Scherrer equation, in X-ray diffraction and crystallography, is a formula that relates the size of sub-micrometre crystallites in a solid to the broadening of a peak in a diffraction pattern. It is often referred to, incorrectly, as a formula for particle size measurement or analysis. It is named after Paul Scherrer. It is used in the determination of size of crystals in the form of powder. The Scherrer equation can be written as: WebWith XRD, the crystallite size can be evaluated using the fact that the full width at half maximum of a diffraction peak is wider as the crystallite size decreases. However, there is a limit in the evaluation of the crystallite size using XRD Between a few nm to a …
