1·Sodium montmorillonite can be freeze-dried into a spongelike material known as an aerogel. Aerogels are famously fragile.
钠蒙脱石能被冷冻干燥成气凝胶——类似海绵状的物质。
2·Aerogel is nicknamed "frozen smoke" and is made by extracting water from a silica gel, then replacing it with gas such as carbon dioxide.
气凝胶的一个绰号是“固态烟”，通过从硅胶中抽去水分代之以气体(比如用二氧化碳)制成。
3·Aerogel is also being used for everyday applications.
气凝胶也正在日常生活中得到应用。
4·Aerogel, one of the world’s lightest solids, can withstand a direct blast of 1kg of dynamite and protect against heat from a blowtorch at more than 1, 300C.
气凝胶，地球上最轻的固体物质之一，能够承受一公斤烈性炸药爆炸的直接冲击，能够抵御喷灯产生的1300度以上的高温。
5·Silica aerogel film is a kind of functional material which has an abroad foreground of applications.
二氧化硅气凝胶薄膜是一种应用广泛的功能材料。
