As we all know, nano aerogels are the lowest density solid known in the world. Generally, more than eighty of aerogels are air, so it looks very "weak". Friends should never "judge people by appearance", but aerogels can accept "little guys" at 1400 degrees Celsius. Someone wants to know how big the hardness of aerogels is.
Aerogels look like "bony", but they are actually very strong. It can withstand pressure thousands of times its mass and melt only when the temperature reaches 1200 degrees Celsius. In addition, its thermal conductivity and refractive index are very low, and its insulation can be 39 times stronger than that of relatively good glass fibers.
Aerogels are of great hardness. They also have beautiful appearance, excellent fire prevention effect and excellent performance. They are really "people can not be looked alike", like ants, looking at small, but some are strength. Ability to withstand 1700 times the pressure equivalent to their own weight.
