one of the most advanced technique for phase determination of different kind of material is Reitveld Refinement Method. In this method , peak profile fitting, size broadening and strain broadening were calculated on the basis of following equations. Where Gik is Pseudo-Voigt function, C0=2, C1=4ln2, H is full with at half maximum of the Kth brag reflection, γ is shape parameter, Xik= (2θi - 2θk)/Hk. Di, ηi, λ, U and W are grain size function, strain function, wavelength, strain parameter and size parameter of peak profile, respectively. In the size and strain functions, i and STD are referred to analyzed and standard samples, correspondingly.
