Do you know the lightest solids in the world?
Putting it on the fluff of the dandelion could not be crushed, the foam sponge was even more incomparable in front of him, she was aerogel.
On the outside, it looks like a cloud and fog, it is very clear, but in fact, it is not made of any special material.
The main component of the glass-like clear gel is silica, but because more than 80% of it is air, the density is only one thousandth of that of glass.
What's the use of asking him? Just light? Of course not, such a small piece of green pepper, seemingly light and fragile, but in fact it is very hard.
In erp experiments, he can withstand pressure thousands of times its own mass, and its thermal insulation effect is first-class. The aerogel after one year of age is equivalent to the thermal insulation effect of twenty or thirty pieces of ordinary glass.
Put it between the flower and the flame, burned at a high temperature of more than 1000 degrees, the aerogel and this flower have not been damaged once, and the all-carbon aerogel in the aerogel species, but the Guinness Certification of the world's lightest solid, 99.8% of which are air cannons, if these air cannons are removed, its solid material density is only 0016 mg, and each cubic centimeter is only 1/6 of the air.
In addition to being light, hard and insulating. The thermal conductivity and refractive index of the seventh grade are also very insulating, and the effect is stronger than the best glass fibers.
The 39th generation can be said to be a collection of thousands of advantages in one old, but do you know if a pound of green pepper and a pound of feathers are lighter than anyone?
