The aim of this study was to optimize the modification of Egyptian kaolinite for application in paper coating. The study focused on four modification methods; sedimentation process, chemical bleaching, calcination, and dealumination. The effect of these methods on the structure of kaolinite was studied using X-ray fluorescence (XRF), X-ray diffractometer (XRD), …
