Thermal treatment of kaolin clay to obtain metakaolin

Thermal treatment of kaolin clay to obtain metakaolin

The metakaolin was produced by thermal treatment (calcination) of the starting high-quality kaolin clay from Serbia. The optimal calcination parameters, for which nearly complete dehydroxylation of the material was achieved, are: temperature 650°C and heating time of 90 min. The conversion of the ka...
