    Kaolinite - Wikipedia

    Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals 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) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

    Mineral: Kaolinite - digitalfire

    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. The attached water both 'glues' particles together and acts as a 'buffer' to lubricate particle-against .

    Kaolin | iMinerals Inc.

    Kaolin. During the weathering of intrusive rocks a process known as "kaolinization" occurs wherein the sodium feldspar breaks down into kaolin group minerals – kaolinite and halloysite. Both are hydrated aluminosilicate minerals. Kaolinite (Al 2 Si 2 O 5 (OH) 4 ) occurs as plate-like sheets that commonly appear as "stacked books".
