摘要： Liquid comprising from 93 to 100 percent by weight alcohol is removed from silica alcogel at subcritical temperature to produce silica aerogel. The silica aerogel produced by the method of the present invention not only has high porosity, but in most instances it also has a narrow distribution of small pore sizes. The silica aerogel is preferably reduced in size so as to form particulate silica aerogel.
摘要翻译： 在亚临界温度下从二氧化硅凝胶上除去包含93-100重量％醇的液体，生成二氧化硅气凝胶。 通过本发明的方法制备的二氧化硅气凝胶不仅具有高孔隙率，而且在大多数情况下也具有狭窄的小孔径分布。 二氧化硅气凝胶的尺寸优选减小以形成颗粒状二氧化硅气凝胶。
