& ..It becameAerogel! Discovered by Dr Samuel Stephen Kistler
BELIEVE IT OR NOTBut Aerogel was a result of a bet
Produced from Silicon Dioxide ( SiO )
First advertised in 1942 under the name of Santocel by Mosanto Corporation.HOW V R Santocel was discontinued in 1970
But every dark cloudhas a silver liningIn the 1980s people started gaining interest in Aero Gels yet again

Since it is non-polar and thus insoluble in water, a solventsuch as acetone or methanol are added for the reaction tooccur.

Inhaling alkoxides of silicons or metals are hazardous.
Alkoxides tend to be very expensive.
Other alternatives : Waterglass Gelation.

2. Energy Absorbing Shock Absorbing Material !
Since it is brittle and has a very low density, the
collapse of the solid network occurs gradually,
spreading the force of impact out for a long time.
Act as a shock-absorbing layer.

3. Surface Chemistry
Supercritical Extraction Process: surface consists
primarily of alkoxy, -OR groups.
Carbon Dioxide Drying: surface exclusively covered by
hydroxyl, -OH groups.
Acidic. Strong hydrogen-bonding effect.
