Kaolin is a mixture consisting principally of the mineral kaolinite and containing varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase. Also known as china clay, kaolin is a soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, drying agents, and many other products.


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.


The classical model is the ‘house of cards’ structure of kaolinite in which the face-to-edge association leads to an open 3D structure (van Olphen, 1965). In the case of smectite-water systems it now seems more likely that the microstructure is mainly controlled by the face-to-face interactions (


The crystal structure displayed to the left, including all H atoms, is based on low-temperature (1.5° K) neutron powder diffraction data (Bish, 1993) instead of the more common x-ray diffraction data that has been used since the time of Linus Pauling’s original determination of the crystal structure of kaolinite

CUFF Geology Department, James Cook University of North Queensland Townsville, Queensland 4811, Australia Abstract- The crystal structure of the kaolinite : dimethylsulfoxide (DMSO) intercalate (P 1, a = 5.187(2),


Understanding the atomic-level changes that occur as kaolinite is converted (thermally dehydroxylated) to metakaolin is critical to the optimization of this large-scale industrial process. Metakaolin is X-ray amorphous; therefore, conventional crystallographic techniques do not reveal the changes in local structure during its formation. Local structure-based experimental techniques are useful


Kaolinite. Kaolinite is one of the simplest clay minerals and it is also very common. In the structure of kaolinite (Fig. 5.18), the SiO 4 tetrahedra are arranged in a hexagonal array, with their bases situated on the same plane and all their vertices pointing in one direction.These apical oxygens substitute for some hydroxyl groups at the base of the octahedral, gibbsite-type layer.

Structure of metakaolinite does not contain OHions, the distance between layers is shorter than kaolinite and also it is more defective and less stable than kaolinite [26].


Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as clay.It is named after Montmorillon in France.Montmorillonite, a member of the smectite group, is a 2:1 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central octahedral sheet of alumina.


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's structure is composed of silicate sheets (Si 2 O 5) bonded to aluminum oxide/hydroxide layers (Al 2 (OH) 4) called gibbsite layers.


The flocculation and solid/liquid separation of four well-characterized kaolinites (2 well, 2 poorly crystallized) have been studied for comparison of surface structure (SEM), aggregate structure during flocculation (cryo-SEM), settling rate, and bed density (with raking). It is shown that major differences in these properties are largely due to crystallinity and consequent surface structure


Structure All clay minerals consist of particles that contain anionic layered silicates and metal cations. They are part of the phyllosilicate group of minerals. Most have the "sandwich" structure with 2 layers of sheet silicates bonded to octahedral cations. Other, weakly bonded cations are located between layers and are solvated by water.
