The kaolinite clay/mica-rich kaolin waste mixture (25 wt% waste) fired at 1400 °C was analyzed by X-ray powder diffraction with Rietveld refinement analysis of the XRD data. Refined (experimental, ...

In this paper, anhydrous pyrolysis experiments were performed on Huadian oil shale kerogen with and without different minerals (calcite, kaolinite, gypsum, montmorillonite) using a Fischer assay ...

Understanding the atomic-level changes that occur as kaolinite is converted (thermally dehydroxylated) to metakaolin is critical to the optimization of this large-scale industrial process. Metakaolin ...

Kaolinite is of low structural order, which was considered the main difficulty in the application of the Rietveld method. Goethite has up to 33 mol% of Al. As observed by scanning electron microscopy ...
