About this site

The main use of the mineral kaolinite (about 50% of the time) is the production of paper; its use ensures the gloss on some grades of coated paper. Kaolin is also known for its capabilities to induce and accelerate blood clotting. In April 2008 the US Naval Medical Research Institute announced the successful use of a kaolinite-derived aluminosilicate infusion in traditional gauze, known commercially as QuikClot Combat Gauze, which is still the hemostat of choice

About this site

Kaolin is not only a raw material for one of the finest products, porcelain, but also a type mineral for a varied spectrum of environments of deposition characterized by a rather sharp upper limit of formation of 390 ± 10 °C at a pressure of 2000 bar. For all geoscientists dealing with processes below this physical-chemical boundary, the role ...

Kaolinite: The clay mineral kaolinite information and pictures

Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.

Bentonite, Kaolin and Selected Clay Minerals (EHC 231, 2005)

3.1.2 Kaolin . Kaolin and the clay mineral kaolinite are natural components of the soil and occur widely in ambient air as floating dust. Kaolinite is formed mainly by decomposition of feldspars (potassium feldspars), granite, and aluminium silicates. It is also not uncommon to find kaolin deposited together with other minerals (illite, bentonite).
