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.
Kaolin, also called China Clay, soft white clay that is an essential ingredient in the manufacture of China Clay offered by us is popularly known as Hydrated Aluminum Silicate. We bring forth Kaolin China Clay that is manufactured from superior quality materials that assure our customers of our authenticity. Finding various applications, our products are utilized in automotive as well as appliances like making of paper, rubber, paint, and many other products. China clays have long been used in the ceramic industry, especially in fine porcelains, because they can be easily molded, have a fine texture, and are white when fired. Additionally, we provide time bound delivery of Calcined Clay Powder in various quantities and packaging to the desired destination. We are reckoned as one of the most eminent Calcined Clay Powder Manufacturers and Exporters from India. Uses It is used in manufacturing of porcelain and chinaware. For this purpose we prefer grit free china clay with some tolerance. It is also utilized in manufacturing of electrical insulators. China clay free from silica and unaltered feldspar is used for electrical insulators. For electrical insulators iron content as low as possible in used china clay. It is also used in production of crockery and paint industry. All users prefer china clay with some tolerance depending upon the end products to be manufactured. In Pharmaceuticals and cosmetic industry china clay is used. They use froth free china clay i.e. the presence of lime should be practically nil.
