Determination of Crystallite-Size of Various Paraffins by X-Ray Diffraction Broadening

It is said that X-ray diffraction broadening is decided by crystallite-size, form, and internal disorder of crystals under constant conditions of experiment. It has been known in general to determine crystallite-size by line-broadening according to the equation proposed by Scherrer.The authors calculated crystallite-size of various paraffins by means of the above method, from the recorded figures of automatic X-ray diffractometer (Geiger Flex).As a result, it was found that the crystallite-size of various paraffins was 250600Å, for which much differences could be by the preparation methods of paraffin samples for the diffractometer.
