What is China Clay (Kaolin)?

China Clay, scientifically known as Hydrated Aluminum Silicate (Al₂Si₂O₅(OH)₄), is a soft white clay formed by the decomposition of feldspathic rocks. It is a naturally occurring mineral that is chemically inert, has low plasticity, and provides excellent whiteness and brightness.

This mineral is widely used as a filler, extender, and coating agent across industries. Its unique combination of chemical inertness and smooth particle structure makes it a valuable industrial material.

Applications of China Clay (Kaolin)

In Ceramics:- China Clay acts as a key raw material in ceramics manufacturing. It gives strength, smoothness, and whiteness to tiles, sanitaryware, and porcelain products.

In Paper Industry:- Used as a coating pigment, China Clay enhances paper brightness, gloss, and printability.

In Paints & Coatings:- Serves as a functional filler in paints, providing better coverage, durability, and scrub resistance.
