摘要： 由高岭土、煤研石合成A型分子筛[1-3],其中所含石英杂质影响分子筛的质量.物理方法不可能完全除去该类矿物中的石英.

关键词: 石英, 高岭土, 转化, 活化, 分子筛

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
