Calcined Kaolin
Calcined Kaolin is a fine, white to off-white powder produced by heating natural kaolin clay to high temperatures (typically between 600°C and 900°C) in a controlled process called calcination. This thermal treatment removes chemically bound water, changes the crystalline structure, and enhances the physical and chemical properties of kaolin. The resulting product exhibits increased brightness, hardness, and opacity, making it highly valuable as a functional additive and filler in numerous industrial applications. Calcined Kaolin is widely used in coatings, ceramics, plastics, rubber, paper, and paint industries to improve durability, brightness, and performance.
