There are several techniques employed to measure crystallite size:
X-ray Diffraction (XRD): This is the most common method, where the broadening of diffraction peaks is analyzed to estimate crystallite size using the Scherrer equation. Transmission Electron Microscopy (TEM): Provides direct imaging of crystallites, allowing for size and morphology analysis. Dynamic Light Scattering (DLS): Used for measuring particle sizes in colloidal suspensions, which can be correlated to crystallite size.
