Calcined Kaolin



Calcined kaolin is produced by heating natural kaolin clay (chemical formula: Al₂Si₂O₅(OH)₄) at high temperatures, typically above 950–1050°C. During this calcination process, the bound water within the kaolin crystal structure is removed, leading to significant changes in its structure and properties. The resulting material exhibits unique physical and chemical characteristics that make it widely applicable across industries.

🔹 Processing Features

1. Dehydroxylation: The calcination removes structural water, converting kaolinite into metakaolin.

2. Phase Transformation: At higher firing temperatures, mullite crystals may form, enhancing refractoriness and strength.

3. Particle Size & Whiteness Control: The product can be ground to fine particle sizes while maintaining high whiteness and chemical stability.

🔹 Key Properties

> High Whiteness – ideal for applications requiring brightness.

> Low Plasticity – reduced shrinkage and warping due to the removal of crystalline water.

> Excellent Refractoriness – thermally stable, resistant to high temperatures.

>Good Opacity & Dispersion – enhances covering power and mechanical performance in coatings, rubber, and plastics.
