Assessment of the quantitative accuracy of Rietveld/XRD analysis of crystalline and amorphous phases in fly ash

Zhao, Piqi; Liu, Xianping; Gomez-de-la-Torre, Maria de los Angeles; Lu, Lingchao; Sobolev, Konstantin (2017)

An internal standard method based on Rietveld/XRD whole-pattern fitting analysis of fly ash is used to assess the quantitative accuracy to determine its crystalline and amorphous phases under various conditions such as ...
Error analysis and correction for quantitative phase analysis based on Rietveld-internal method: Whether the minor phases can be ignored?

Zhao, Piqi; Lu, Lingchao; Liu, Xianping; Gomez-de-la-Torre, Maria de los Angeles; Xin, Cheng (MDPI, 2018-02)

The Rietveld-internal standard method for Bragg-Brentano reflection geometry (q/2q) X-ray diffraction (XRD) patterns is implemented to determine the amorphous phase content. The effect of some minor phases on quantitative ...
