Calcined kaolin

Calcined Kaolin
Calcined Kaolin is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.

Application

Our calcined kaolin is mainly used in the fields such as paint, paper, rubber, engineering plastic, cable, ink to replace TiO2 and cut cost.

 

Paper Industry: 

The primary use of kaolin is in the paper industry.  It serves as a paper coating which improves appearance by contributing to brightness, smoothness and gloss.  It also improves printability.  Additionally, it is used by the paper industry as a filler reducing cost and the use of tree-based resources.

 

China, Porcelain and Tableware:

Many people are under the mistaken impression that the only use for kaolin is in the manufacture of china.  This is not true, and its use by the paper industry far exceeds its other uses.  However, kaolin still serves as a valuable component in china and other tablewares.  Its color, gloss and hardness are ideal characteristics for such products.

 

Other Uses:

Kaolin has a variety of other uses in products including paint, rubber, cable insulation, specialty films and fertilizers.  New uses are being discovered frequently, and ensure that the mineral will remain in demand for a long time.
