Introduction The X-ray diffraction method was first used to determine the ideal composition of a material, and Von Laue made the first discovery of X-ray diffraction in 1912 when he found that the incident rays from a crystal might be diffracted by the surroundings, in the years that followed, this technique has been widely used in scientific and applied fields A practical way for figuring out the average size of nanocrystallites in bulk nanocrystalline materials is x-ray diffraction, the scientist, Paul Scherer, presented his results in 1918 and included an equation in the name of Scherrer [4].	cache/iajs-3393.pdf	txt/iajs-3393.txt
