Calcined Kaolin
Manufacturer in India
Puresil India is among the trusted calcined kaolin manufacturers, producing high-quality calcined kaolin designed for demanding industrial applications. Using controlled thermal processing, we transform high-grade natural kaolin into a non-hydrated, amorphous alumino-silicate with enhanced whiteness, hardness, opacity, and thermal stability.
With strong reserves, advanced processing facilities, and reliable logistics, we supply calcined kaolin to customers seeking consistent quality and long-term supply assurance.
What is calcined kaolin
Calcined kaolin is produced by heating refined kaolin clay at temperatures ranging from 900°C to 1100°C. This calcination process removes structural water and alters the mineral structure, resulting in a material with improved optical, mechanical, and insulating properties.
Compared to raw kaolin, calcined kaolin offers higher brightness, better opacity, lower loss on ignition, and improved performance in high-temperature and high-specification industrial environments.
