China Clay or Kaolin is one of the purest form of clays, composed chiefly of the mineral kaolinite, usually formed when granite is changed by hydrothermal metamorphism. Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra. Kaolinite has a low shrink - swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow or light orange colors. Commercial grades of kaolin are supplied and transported as dry powder, semi-dry noodle or as liquid slurry. Salient Features Contributes in improving the chemical resistance, electrical properties and reduction in water absorption Lowers the crack tendency in the finished products Improves shock resistance as well as surface quality

What is China Clay? China Clay has the chemical Al2Si2O5(OH)4. It is also known as Kaolin, and is a soft white clay used in the production of ceramic tiles. It is a valuable industrial metal. China clay was first discovered in the 1740s in England. It gets its name from a hill in China called Kao-ling, where it has been collected for centuries.

China clay
China clay is also known as white clay. Primary clay formed by natural kaolinisation process. China Clay is naturally occurring hydrated Aluminium Silicate. It is formed by decomposition of some part of feldspar mineral.White in color , Used in ceramic slip casting process, Pressing processes and forming process as a body former and filler. It mainly has oil absorbing properties, reduced shine and translucent properties. It also provides hiding effect and reduces the usage of TiO2 to a great extent.

China clay is also called "kaoline", it is one of the essential raw material for ceramic industries, china clay does not swell on adding water & alumina present in clay do not form isomorphous series with any other metallic compound. China clay is a naturally hydrated aluminum silicate. It is one of the most abundantly available clay in the earth's crust. A large variety of china clay is mined all over india. Application: potteries, tiles, ceramics, paint, paper & plastics.
