Kaolin, also called China Clay, soft white clay that naturally occurs from Hydrated Aluminium Silicate crystalline mineral. It is characterized by its lamellar, leaf shape, and chemical inertness. The combination of platy shape and fine particle size results in improved characteristics and makes it suitable in many industries. Kaolin is used for its whiteness and purity.
Kaolin, or ‘china clay’ as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape, and chemical inertness. Metakaolin is manufactured by the calcination of kaolin to form an amorphous pozzolanic white mineral additive for use in cement-based products. Calcined Kaolin is an anhydrous aluminum silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.
