Abstract: In the present paper the reaction process of alkali roasting of simulated samples and kaolinite minerals was studied.TG, DTA and XRD were used to follow the phase transitions and the resultant product species during the alkali roasting. Reactivities of the conversion products were tested and verified through synthesis of molecular sieves, hence clarifying the inter-relationship between active ingredients and alkali roasting conditions.

Key words: quartz, kaolin, conversion, activation, molecular sieve
