WebAug 21, 2024 · Grain size is the diameter of singular sediment grains, or the lithified particles in clastic rocks. The term may apply to other granular materials, too. This differs from the size of a crystallite, which refers to the size of a single crystal within a particle or grain. Many crystals can be composed of a single grain. WebMatch! can estimate the crystallite size in your sample using Scherrer's formula [1,2]: Crystallite size (average in Å) = K λ / (FWHM * cos θ) where K is the so-called "Scherrer constant" (typically =0.94 for FWHM of spherical crystals with cubic symmetry), λ is the wavelength of the radiation and θ is the diffraction angle of the peak.

The prepared samples were characterized by powder X-ray diffraction analysis (XRD) and confirm the formation of single phase NiFe2O4 compound with cubic structure. The average crystallite size was … WebGrain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals. ...
WebCrystallite size is the effective size of the coherent diffracting domains within a polycrystalline specimen. Microstrain is the degree of distortion present in the crystalline lattice. Both crystallite size and microstrain in the crystal lattice affect the broadening of the X-ray diffraction lines.
