Kaolin is a name given to a group of phyllosilicate minerals whose layers have a 1 : 1 structure with a composition of Al 2 Si 2 O 5 (OH) 4. The 1 : 1 designation indicates the individual layers are composed of sheets of corner sharing tetrahedra in a distorted hexagonal arrangement and a sheet of edge sharing octahedra.

Metakaolin. Jamal M. Khatib, ... Adel A. ElKordi, in Waste and Supplementary Cementitious Materials in Concrete, 2018 Abstract. Metakaolin (MK) is one type of calcined clay and it comes from the calcination of kaolin clay, and there have been some interests in the use of MK in recent years (Siddique and Klaus, 2009). For example in the United Kingdom, the …

Kaolinite is a pure clay mineral crystal of one part alumina and two parts silica. Most other clay minerals are derivatives of kaolin. Kaolin particles are flat and comparatively the largest of all clay minerals, this makes them among the least plastic. They have a surface chemistry that gives them an affinity for water.

Kaolin, or 'china clay' as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape and chemical inertness.
