Use of Computer Analysis for X-ray Diffraction Data

Abstract

Norio lwashit X-ray dill faction technique, have widely been ftpplicd for crystal structure charactcniation of carbon material , and ga c useful information. Progresses, in computer. were remarkable. which made the measurement cI diffrac-tion intensities and their correction, on di fferent [actors easier. It vf aS pointed out, therefore, that the procedures I or X-ray diffraction measurements, e to he revised so as to take into account of these progresses in computation. In the present paper, computer analysts of digital data of X-ray WI Iraction, for instance, determination of lattice constants and crystallite size of carbon materials iGakushin method I using profile fitting technique and calculation of integral intensity in the case of estimation of graphititation degree PI was reviewed. The measurement conditions to obtain a good digital diffraction data, the procedures of smoothing and intensity correction of diffraction profile were introduced.
