kaolin manufacturing proces
Metakaolin
It is produced by heating kaolin, a natural clay mineral, to temperatures typically between 650°C and 750°C. At such temperatures, the kaolin is dehydroxylated, transforming from kaolin (Al 2 Si 2 O 5 (OH) 4 or AS 2 H 4) to metakaolin (Al 2 Si 2 O 5 or AS 2). This process results in a disordered structure and a highly reactive, amorphous ...
