CALCINED KAOLINITE Pennsylvania State University

CALCINED KAOLINITE. Composition. Kaolin is a clay composed primarily of the hydrated aluminosilie mineral kaolinite (Al 2 O 3. 2SiO 2. 2H 2 O) with minor amounts of quartz, feldspar, mica, chlorite and other clay minerals. It is distinguished from other clays by its softness, whiteness and ease of dispersion in water.

Weathering & Clay Minerals Tulane University

Kaolinite is formed by weathering or hydrothermal alteration of aluminosilie minerals. Thus, rocks rich in feldspar commonly weather to kaolinite. In order to form, ions like Na, K, Ca, Mg, and Fe must first be leached away by the weathering or alteration process. This leaching is favored by acidic conditions (low pH).
