Kaolinite (/ ˈ k eɪ. ə l ə ˌ n aɪ t,-l ɪ-/ KAY-ə-lə-nyte, -lih-; also called kaolin) [5] [6] [7] is a clay mineral, with the chemical composition Al 2 Si 2 O 5 4. It is a layered silicate mineral , with one tetrahedral sheet of silica ( SiO 4 ) linked through oxygen atoms to one octahedral sheet of alumina ( AlO 6 ).
The dehydroxylation of kaolin to metakaolin is an endothermic process due to the large amount of energy required to remove the chemically bonded hydroxyl ions. Above the temperature range of dehydroxylation, kaolinite transforms into metakaolin, a complex amorphous structure which retains some long-range order due to layer stacking. [ 2 ]
Kaolin was also used to treat cholera around the start of the 20th century. ... it physically binds to acids and toxic substances in the stomach and digestive tract.

Kaolin clotting time (KCT) is a sensitive test to detect lupus anticoagulants. [2] There is evidence that suggests it is the most sensitive test for detecting lupus anticoagulants. [ 3 ] It can also detect factor VIII inhibitors but is sensitive to unfractionated heparin as well.
Geophagy in non-human primates is primarily used for protection from parasites, to provide mineral supplements and to help metabolize toxic compounds from leaves. [4] Geophagy also occurs in humans and is most commonly reported among children and pregnant women.
