【摘要】 利用红外分析法(IR)对3类地聚合物结构链上的Si和Al的价键状态、周围化学环境进行了分析,同时也探讨了地聚合物与同组成的沸石晶体之间的关系。实验结果表明,地聚合物在合成过程中AlO4四面体键接在SiO4四面体链上,共同构成了地聚合物的三维网状结构;地聚合物与同组成的沸石晶体在合适的条件下可以相互转化,揭示出地聚合物可能为同组成沸石晶体的前驱产物。更多还原

【Abstract】 The structure,bonding state and ambient atmosphere of Si and Al of three types of geopolymers were investigated by using infrared ray（IR） analysis.The relationship between geopolymers and the corresponding zeolite crystals with the similar chemical composition was also discussed.The infrared evidence showed that SiO₄ tetrahedral chain was bonded by AlO₄ during the process of geopolymerisation reaction,and the two types of tetrahedral jointly form the three dimensional framework structure of geopolymers.The mutual transformation between geopolymers and zeolite crystals can be realized under suitable condition,which revealed that geopolymers may be the precursors of the corresponding zeolite crystals.更多还原
