Aerogel Nanogel NEU!

You get a bottle with about 10ml Aerogel granules – particle size 1 – 3mm

Es ist der leichteste und dichteste bekannte Feststoff und steht mit 15 Einträgen im Guinness-Buch der Rekorde, including best insulator and lowest density solid.
Aerogel is composed of 99.8% air and is chemically similar to ordinary glass.

It is nicknamed frozen smoke, solid smoke or blue smoke due to its semi-transparent nature and the way light scatters in the material; however, it feels like expanded polystyrene (Styrofoam) to the touch.

 

Silica aerogel strongly absorbs infrared radiation. It allows the construction of materials that let light into buildings but trap heat for solar heating. It has extremely low thermal conductivity (0.03 W?m/m2?K bis zu 0,004 W?m/m2?K, was ihm bemerkenswerte Isolationseigenschaften verleiht. Sein Schmelzpunkt liegt bei 1.473 K (1.200 ?C oder 2.192 ?F). Silica-Aerogel kann die menschliche Hand vor der Hitze eines Schneidbrenners aus nächster Nähe schützen.
