摘要
目前硅气凝胶是世界上最轻、隔热性最好、孔隙率较高且声传播速率较低的固体材料,由于其特殊的网络结构使其具有很多独特的性能。本文从其研究历史及现状出发,对其性能以及在不同方面的应用和制备原理进行了综述,并对其广阔的发展前景进行了展望。
Presently, silica aerogels are the lightest solid material which have the best property in thermal insulation and have the higher porosity, the lower sound velocities in the world, The silica aerogels have many unique properties owing to their special structure. This paper began from the history and the study nowadays of silica aerogels, then their properties, their application in different aspects and their prepared principle were summarized and their prospect of development had been proposed.
