Properties Extremely low

density Very good thermal

insulator High specific

surface area Lowest dielectric

constant

Introducing Metal Aerogels!• Inorganic cousins of

the more common Silica Aerogel

• Until very recently, Metal Aerogels did not exist!

What are its properties?

High specific surface area (100-500m2/g)

Electrically conductive!

Enhanced catalytic activity

Surprisingly capable thermal insulator
