Kaolin (Calcined Kaolin)
Kaolin, also known as china clay, is a naturally occurring clay mineral composed predominantly of kaolinite. When calcinated, kaolin becomes calcined kaolin, which is formed by heating the clay to high temperatures, enhancing its properties and making it suitable for various industrial applications. Calcined kaolin is known for its whiteness, fine particle size, and excellent absorbency, making it a valuable ingredient in numerous products.
