Crystallite Size and StrainUCL

For real powder samples and diffractometers this limit is reached when the crystallite size, L, is around 1-10 μm (or larger). So the use of peak broadening to determine crystallite size is normally limited to cases where the average crystallite size is ≤ 1 μm. Strain

Grain growth and grain boundary diffusion involve similar atomic jumps during sintering. Atoms moving across the boundary cause grain size changes, while atoms moving along the boundary cause densification. It is no surprise that grain growth and densification have very similar dependences. Further, it is difficult to separate the two events.
