Product Overview
Calcined kaolin is a type of kaolin clay that has been thermally processed (calcined) at temperatures around 900–1100°C, transforming it from its natural hydrated form into a non-hydrated, amorphous alumino-silicate. This heating process enhances its whiteness, hardness, opacity, and insulating properties, making it suitable for a wide range of high-performance applications.
