Is possible find surface area from XRD?
if possible means, how to calculate it ?
Dear Sivaraj,
Yes, you can find out the specific surface area (instead of surface area) of the sample which could be in film form. Specific surface area (SSA) describes the properties of the material and determines its type and structure. Practically this quantity may be used for analyzing reactions on surfaces, adsorption and heterogeneity of the sample.
SSA = (6 * 〖10〗^3)/(τ * ρ)
where τ is the size of the crystallite and ρ is the density of the used experimental samples. The size of the crystallite can be measured with the help of XRD.

Check out the Scherrer equation, which, assuming spherical particles, should give you a diameter, from which you can calculate a surface area.
