Preparation Characterization of Activated Kaolinite

2016-1-6  Calcination of china clay was carried out at a temperature of 750°C to form metakaolin. The chemical analysis results of raw clay sample showed that the clay is composed of alumina and silica. Activated clay was synthesized by acid and alkali leaching process of metakaolin. Two strong acids HCl and H 2 SO 4 were used for acid activation and ...

Calcined Kaolin‎ Chamotte Clay AIMR

Calcination Process. Using extremely high temperatures reaching 1400 ˚C in 92m long rotary kiln to remove some unwanted elements and to alter the properties of minerals, the calcination of kaolin generally increases hardness and alters the electrical properties of the material. The process also leaves the Kaolin anhydrous (without water).
