China Clay
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.
China Clay is the heart of potteries, tiles, ceramics, and many other industries.
