| 摘 要： | 二氧化硅气凝胶由于其特殊的网络结构使其具有密度小、隔热性好、孔隙率高、比表面积大、传声速率低等优良性能。从1931年开始，经过广大研究者几十年的深入研究，二氧化硅气凝胶有了更广阔的发展。本文介绍了以不同原料制备二氧化硅气凝胶的方法，论述了二氧化硅气凝胶的干燥技术，概述了二氧化硅气凝胶的改性措施，分析了二氧化硅气凝胶的应用前景。

| Abstract: | The special network structure of silica aerogels makes it possess good performances of small density, good thermal insulation, high porosity, large specific surface area, low sound transmission rate, etc. From the year of 1931, silica aerogels have been developed broaderly. In this paper, the preparation methods of silica aerogels with different raw materials have ben introduced, the drying technologies of silica aerogels discussed, the silica aerogel modification measures have been outlined, the applications of silica aerogels have been analysed. |
