摘要：

氧化硅-氧化铝（SiO₂-Al₂O₃）体系凝胶不仅应用广泛,而且其制备及反应机理还可借鉴到碱激发胶凝材料等领域。通过对溶胶-凝胶法合成氧化硅-氧化铝体系凝胶的制备过程及影响因素和影响规律、凝胶的性质和结构表征及合成机理研究进展进行综述,提出目前仍缺乏有关碱（土）金属离子对凝胶结构性能的影响研究以及硅铝含量变化的定量描述数据,建议拓宽研究范畴,结合核磁共振等检测方法,得出该体系结构性能变化准确数据,为氧化硅-氧化铝体系凝胶的设计和应用夯实基础。

Abstract:

The SiO₂-Al₂O₃ system gel is not only widely used,but its preparation and reaction mechanism can also be used in alkali activated cementitious materials and other fields.Through the preparation process of SiO₂-Al₂O₃ system gel by sol-gel method,the influencing factors and rules,the properties and structural characterization of gels and the research progress of synthesis mechanism were reviewed.It was pointed out that the influence of alkali（earth） metal ions on the structure and pro-perties of gelatin and the quantitative description data of silicon and aluminum content were still lacking.It was suggested to broaden the scope of research and combine nuclear magnetic resonance and other detection methods to get the accurate data of the structural performance of the system,which would build a solid foundation for the design and application of SiO₂-Al₂O₃ system gel.

Key words: sol-gel method, SiO₂-Al₂O₃ system gel, preparation, synthesis process
