Aerogel, the Coolest Solid!

Frozen smoke is really amazing. With the lowest density, highest thermal insulation, lowest refractive index, and highest surface area per unit volume of any solid, it exhibits a remarkable range of properties which are not encountered in any other kind of material.

Some of it's properties include:

  • Density: 0.1g/cm3

  • Surface Area: 600-1000 m2/g

  • Percent Solid: 2-5


Here's some pics demonstrating it's transparent nature:
