Hence, the x-rays produced during the cascade are usually energetic enough to escape from the sample itself and can be, therefore, detected by the detectors. WebbThe Scherrer equation can be used to determine the crystallite size. It uses a shape factor in x-ray diffraction and crystallography to correlate the size of sub-micrometre particles, or crystallites, in a solid to the broadening of a peak in a diffraction pattern. In the XPowder software, this equation is [1,2,3,4]:
