Here are three different ways to calculate crystallite size and lattice strain of a sample, based on XRD peaks: "Scherrer" calculation, "Williamson-Hall" or "Rietveld".
Each calculation is proper for what kind of combination, grain size and method? what are the limitations and drawbacks of each method?
I have high energy ball milled of pure Magnesium+ 1%wt of Calcium; with final grain size of about 7-70 micron.
What kind of analysis should I use to calculate crystallite size and lattice strain?
Any better suggestions?
All the three mehods namely Scherrer, Williamson-Hall and Rietveld are good to measure crystallite size and strain. It depends on morphology and type of material. It is always suggested to do the TEM analysis of your samples to get complementary results.
Rietveld is more accurate, but the calculation by any of these methods pours in the end in one direction, and all serve the same purpose.
Dear Parisa Golmohammadi you can easily calculate crystallite size by visiting the below-mentioned link
