kaolin
Kaolin is an aluminosilicate soft white mineral named after the hill in China (Kao-ling) from which it was mined for centuries. In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, and varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase.
Description
Color Dark White, sometimes red, blue or brown tints from impurities.
Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6). Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white grades, mineral (decahedral phyllosilicate clay), produced by the chemical weathering of aluminum silicate minerals like feldspar. Commercial grades of kaolin are supplied and transported as dry powder.
