Scherrer method
Scherrer method One possible method of calculating crystallite size from XRD line broadening is to use the method developed by Scherrer in 1918, which uses the Scherrer equation: Dv = Kλ / (β cosθ) where Dv = Crystallite size weighted by volume, K = Scherrer constant (somewhat arbitrary), λ = wavelength of radiation, and β = integral breadth of peak (in radians 2θ) located at angle θ. This appro..
