We offer Calcined kaolin which is a hydrous, thermally structured aluminum silicate, produced by heating ultra-fine natural kaolin at a very high temperature.The calcination process changes the shape of kaolin particle and increases its hardness. During the calcination process of kaolin, dehydroxylation takes place and leads to the formation of METAKAOLIN, which is a highly reactive substance.

Aug 01, 2003· Kaolin clay is commonly differentiated as "hard" clay or "soft," according to terminology borrowed from the rubber industry. Hard clay is relatively poorly crystallized, very fine-grained kaolin, about 0.2 to 0.4 æm median particle size by sedimentation. It provides reinforcement in rubber, resulting in hard, uncured compounds.

Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.
