What is Calcined Kaolin?

Calcined Kaolin is a processed form of kaolin clay produced by heating high-quality hydrous kaolin at controlled temperatures. During the calcination process, chemically bound water is removed from the kaolin crystal structure, transforming it into a highly functional mineral with improved physical and optical properties.

This thermal treatment significantly enhances:

• Brightness

• Whiteness

• Opacity

• Hardness

• Electrical Properties

• Reinforcement Characteristics

• Chemical Stability

Unlike hydrous kaolin, Calcined Kaolin possesses a modified structure that makes it particularly valuable in coatings, polymers, ceramics, rubber compounds, and construction products.

Because of its superior performance characteristics, calcined kaolin has become one of the most widely used specialty industrial minerals globally.
