Abstract
Kaolinite has been hydrothermally zeolitised in caustic to generate tw o different zeolites-sodalite hydrate and Na 4A. Conditions favouring the formation of the above two zeolites using kaolinite have been esta blished. Under controlled conditions partially zeolitised(sodalite hyd rate) kaolinite has been prepared and examined for thermal stability. It is observed that kaolinite in the presence of sodalite hydrate is u nstable at temperatures above 400 degrees C. This has been attributed to the reaction of kaolinite with entrained caustic in the sodalite hy drate structure.
