WebCrystallite size. 7.8.3.2.2. Crystallite size. There are several diffraction approaches to studying the crystallite size of ceramic materials, ranging from traditional to new. Crystallite size is the size of a single crystal domain inside the particles or grains. A grain can be composed of several crystals.

WebAug 28, 2015 · The distribution of crystallites is estimated and presented in the inset of Fig. 2 a. The size of crystallites is found to be dominantly in the range 20–30 nm with average size 25 nm. The average crystallite size measured from the XRD is 30 nm; hence, there is good agreement between the XRD analysis and TEM observations.
