WebIn common materials, crystallites are large enough that grain boundaries account for a small fraction of the material. However, very small grain sizes are achievable. In nanocrystalline solids, grain boundaries become a significant volume fraction of the material, with profound effects on such properties as diffusion and plasticity.

WebA crystallite is defined and perceived as a coherently diffracting domain (i.e. in principle a single crystal). This is what we generally calculate … WebCrystallites are coherent diffraction domains in X-ray diffraction. Particles are chunks/pieces (usually very small, below 1 mm) of solid matter, ensembles of atoms. Particles can be as small as two atoms (the nitrogen particle for example, [math]N_ {2} [/math]) Grains are volumes, inside crystalline materials, with a specific orientation.
