WebAbstract Scherrer Equation, L=Kλ/β .cosθ, was developed in 1918, to calculate the nano crystallite size ( L) by XRD radiation of wavelength λ (nm) from measuring full width at half maximum of peaks ( β) in radian located at any 2θ in the pattern. Shape factor of K can be 0.62 - 2.08 and is usually taken as about 0.89.

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 … See more The Scherrer equation is limited to nano-scale crystallites, or more-strictly, the coherently scattering domain size, which can be smaller than the crystallite size (due to factors mentioned below). It is not applicable to grains … See more To see where the Scherrer equation comes from, it is useful to consider the simplest possible example: a set of N planes separated by the distance, a.
