china clay cake

Kaolin, also known as china clay, is a natural clay formed by weathering of felspars.It is relatively pure clay predominantly consisting of kaolinite (Al2O3.2SiO2. 2H2O), associated with other clay minerals like dickite, halloysite,nacrite and anauxite. Kaolin is commercially valued for its whiteness and fine particle size which distinguish it from other clays, such as, ballclay and fireclay.

Other physical characteristics that influence commercial utility include brightness,glossiness, abrasiveness and viscosity. The major use of crude china clay is in Cement Industry and of processed china clay is in Ceramic Industry,Paints,Paper and Rubber industires.

The product manufactured by the unit is finished china clay in levigated cake form.

china clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing Al2O3.2SiO2.2H2O.

The product has a multi industrial use. It can be said that the china clay is used from slipper of a feet to a hair dye of a head. The china clay can be used in most of the items to economy the cost of the items.


China clay (kaolin) is used in a number of industries in both crude and processed forms. The major use for crude china clay is in the Cement Industry, whereas Ceramic Industry accounts for consumption of a major share of processed form of china clay. Besides ceramics,processed china clay finds use in other industries, such as sealants, paper coatings,as extender in fibre glass, paint and as a filler for paper, rubber, plastic, cosmetics, pharmaceuticals and textiles. Crude china clay also finds use in Insecticide and Refractory Industries. Other uses of china clay are in ink, ultramarine, synthetic zeolite, catalyst, water filter candles, soaps & detergents and explosives & pyrotechnic industries.
