Dear Nikhil Thota,

you can use he Scherrer equation but have in mind that if you have the size along one specific direction, depending of the difraction peaks used in the calculations.

Regards,

Fernando

See the site below to see the equation and how to use it.

hi

It is possible to find the crystallite size of particles from an XRD profile. There are a few methods available for this:

1. Scherrer method

2. Williamson- Hall plot method

3. Size strain plot method.

you can refer these methods in the following

Article Impact of crystalline defects and size on X-ray line broaden...

After Fernando and Evan , also you can look at the RG link below, it contain dense bundle of knowledge on how to obtain particles size using the XRD data.
