WebJul 30, 2014 · The results showed that the crystallite size estimated from Scherrer’s formula, Williamson–Hall plots and size–strain plot, and the particle size estimated from Transmission electron microscopy analysis are very much inter-correlated. ... This strain may be due to the lattice shrinkage that was observed in the calculation of lattice ... WebWhat is crystallite size and particle size? Crystallite Size,& Grain Size are one and the same but particle size consist of no. of grains or crystallites. Crystallite Size or Grain Size can be calculated using Scherrer formula D = 0.9 λ/ β cosθ where λ – wavelength of X-ray, β- Full Width Half Maxima and θ is Bragg’s angle of diffraction.

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.
