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.
Clay minerals are divided into four major groups. These are the important clay mineral groups: The Kaolinite Group This group has three members (kaolinite, dickite and nacrite) and a formula of Al2Si2O5(OH)4.The different minerals are polymorphs, meaning that they have the same chemistry but different structures (polymorph = many forms).
Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood).

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.
Kaolinite has a hardness of 1 on the mineralogical scale and a density of 2, 540–2, 600 kg/m 3. It is greasy to the touch. It is greasy to the touch. In heating to 500°-600° C, it loses water, and at 1,000°-1, 200° C, it decomposes, liberating heat and forming initially sillimanite and then mullite.

Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity, making it ideal for many industrial applications. Uses During 2013, 48% of Kaolin was used in paper production, and 52% was used for ceramics, light bulbs, paint, rubber, adhesives, smoking pipes, white wash in masonry, absorbents, and in soap.
Kaolinite, which is named for its type locality, Kao-Ling, Jianxi, China; is a common phyllosilicate mineral. It lends it name to the Kaolinite Group, members of which also belong to the larger general group known as the Clays.

Kaolinite, by name, was known since the Yuan (Mongol) dynasty in the thirteenth century as 'Kaolin earth' and was first properly described by Song Yingxing in 1637 in his book Tian Gong Kai Wu (translated: 'Introduction to Heaven's Handicrafts' or 'The Exploitation of the Works of Nature').
Kaolin is used in paper filler and coatings, in cosmetics, in ceramics as well as ceramic proppants, in addition to many filler or absorbent applications. Pure kaolin is a relatively soft mineral, with a Mohs hardness of 2 – 2.5.
Aluminium silicate, also referred to as aluminum silicate, is a compound made from aluminum, oxygen and silicate that can take the form of a mineral as well as combine with water to make a clay. It has a hardness of 1-2 on the Mohs scale of mineral hardness.
Kaolin is a type of clay. Clay is a type of sedimentary rock. Therefore kaolin is a sedimentary rock.
