4.Application:
Calcined kaolin is widely used in the variety of fields.
Its use ensures the gloss on some grades of Paper. Calcined kaolin is the main component of Ceramics.
It is used as filler in Cosmetic.
Calcined kaolin is also used in different electronic component as shock resistance. It mainly used to making fuse, electrical components, wire coating and other electrical components for safety purpose.
It is used in paint to extend the titanium dioxide white pigment and modify gloss levels.
In plastics and cable industry,it can improve the strength and modulus.
Calcined kaolin is used for modifying the properties of rubber upon vulcanization.
In organic farming,it used as a spray applied to crops to deter insect damage.
