Kaolinite Properties, Occurrence and Uses Area

Grinding kaolinite results in the formation of a mechanochemically amorphous phase similar to metakaolin, although the properties of this solid are quite different. Great energy is required to convert kaolinite into metakaolin. Drying. Below 100 °C (212 °F), exposure to dry air will slowly remove liquid water from the kaolin.

Decomposition of Minerals by Grinding

kaolin-2.6, muscovite-2.9, and montmorillonite-2.0. The muscovite and montmorillonite increased slightly in average particle size over a short period of grinding (Fig. 1). The average particle sizes after two weeks of grinding of the three clay minerals were of the same magnitude. The original samples of kaolin and montmorillonite had been passed
