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
Ball Clay is a variety of Kaolinite, like china-clay. It differs from china-clay in having high plasticity and less refractoriness. In chemical composition, ball and china clays do not differ greatly except that the former contains a larger proportion of silica. It has derived its name from the practice of removing it in the form of ball-like lumps from the clay pits in the UK. Ball clays are kaolinitic sedimentary clays that commonly consist of 20-80% kaolinite, 10-25% mica, 6-65% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters. Ball clays are relatively scarce deposits due to the combination of geological factors needed for their formation and preservation.
China clay powder
China clay
China clay or 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, and many other products. In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite.
Ball clays are kaolinitic sedimentary clays that commonly consist of 20-80% kaolinite, 10-25% mica, 6-65% quartz. Localized seams in the same deposit have variations in composition, ncluding the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. Because of High plasticity;High unfired strength;Highly controlled rheological properties;Controlled organic content ball clay is widely use in ceramic. Chemical formula :- Al2O3. 2SiO2.2H2O.
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. Chemical formula :- Al2O3. 2SiO2.2H2O. Application : Pottery Sanitaryware Tiles Dinnerware Production Paper Industry Refractory Rubber Industry Textiles Industries Pottery Works
