Peak broadening due to crystallite size

For real powder samples and diffractometers this limit is reached when the crystallite size, L, is around 1-μm (or larger). So the use of peak broadening to determine crystallite size is normally limited to cases where the average crystallite size is ≤ μm. Strain due to the result of reduction inside the lattice values is ε = 3. Scherrer_equationen.
