Different methods widely used in X-ray diffraction crystal size estimation are compared and these are based on the method of Scherrer, Monshi-Scherrer, Halder-Wagner, Williamson-Hall and Whole Powder Pattern Fitting of PDXL Software Rigaku. FE-SEM (Field Emission Scanning Electron Microscopy) analysis was used as a method of comparison of the results obtained by the different methods applied from the accuracy parameter.The Monchi-Scherrer method is easy to use and the error decreases by applying the linear adjustment by least squares. The trend line intercept provides a more accurate crystal size value. The Halder-Wagner Method is constructed assuming a broadening of the diffraction peak is Voight's symmetric function and the adjustment of the trend line by least squares generates high dispersion in the points and the slope of the line provides a value of less accurate as size crystal. The Williamson-Hall Method considers peak broadering as a function of the diffraction angle that is expected to be the result of the combination of broadening and strain broadening and the adjustment of the line by least squares gives a value of crystal size from the slope quite far from FE-SEM. In conclusion, it is obtained that it is the Monshi-Scherrer method is the most accurate method.
