China Clay/Kaolin

We are engaged in offering a quality range of China Clay/Kaolin which is an igneous feldspar rock also termed as natural mineral generally found in partly decomposed granite. Our organization deliver China clay which is known for its purest form primarily composed of mineral kaolinite which is formed during granite hydrothermal metamorphism. According to its chemical property , it contains Al2O3.2SiO2.2H2O which is a hydrated aluminum silicate.

 

Chemical Name: Anhydrous Aluminum Silicate
Chemical Formula: 2H2O* Al2O3 * 2SiO2 or H4 Al2 Si2 O9)

Chinaclay commercially known, as Kaolin is natural clay formed by weathering of felspars. Chinaclay is a unique industrial mineral containing predominantly kaolinite which is chemically inert, white in colour and exhibits fine particle size. The properties can be improved further in subsequent processing.

Its major uses are in ceramic, paper, paint, rubber & plastic and refractory. Minor uses are in insecticides,pharmaceuticals, cosmetics, textile, cement, ink, ultramarine, fiber- glass, soaps & detergent and explosive & pyrotechnic Industry.
