CALCINED KAOLINITE. Composition. Kaolin is a clay composed primarily of the hydrated aluminosilicate 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. ...

Kaolin is one of the more important industrial clay minerals. Kaolin is comprised predominantly of the mineral kaolinite, a hydrated aluminum silicate. Kaolinite, which is the dominant mineral in kaolin deposits, is a common clay mineral, but the relatively pure and commercially useable deposits are few in number. ... Calcined kaolin …

KAOLIN is a hydrated silicate aluminium crystalline material, which is produced over millions of years by the hydrothermal decomposition of granite minerals, or 'china clay,' as it is widely called. The fine particulate scale, platform or lamellar particle shape and chemical inertness define the hydrous kaolin. Metakaolin is processed to create an …

Notes. Kaolin is pure clay mineral, having a fired chemistry of 1 molar part Al 2 O 3 and 2 parts SiO 2. However the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity. Calcining the material removes that water and destroys the plasticity. Calcined kaolin is not commonly used in traditional ...
