Shape factor scherrer equation

WebbThe Scherrer equation can be used to determine the crystallite size. It uses a shape factor in x-ray diffraction and crystallography to correlate the size of sub-micrometre particles, or crystallites, in a solid to the broadening of a peak in a diffraction pattern. In the XPowder software, this equation is [1,2,3,4]: WebbX線回折とX線結晶構造解析における形状因子(けいじょういんし、英語:shape factor)とは、固体中に含まれる結晶子の大きさと回折パターンのピーク幅との関係 …
