Aerogel
What it is?
Is a coloidal material such as gel, in which the water particles are replaces by a gas giving it a low density and a low thermal conductivity
History
Was created by Samuel Stephens Kistler in 1931
Then Kistler create aerogels based on alumina, chromia and tin dioxide
Advantages
Low thermal conductivity
Low density
Transparent
Acoustic insulation
Silica-based aerogels
Thermal protective
At ambient temperature, pressure and humidity
Low conductivity
Minimun thermal energy exchange
Flame retardant property
Blocks heat transfer
Prevents heat tranfer by convection
Absorbs infrared radiation
Little dense
Doesn't allow air circulation
Use in protective suits
Aerogel-treated clothing prevents burns
Slows down the flame
Offers better thermal insulation properties
Firefighter uniform
Viewfinder
protect the eyes from any harmful substance
Helmet
protects the rescuer from any unforeseen impact on the skull
Jacket
the objective of maintaining regulated body temperature, in addition to resisting the flames of a fire.
Boots
help the rescuer navigate rough surfaces with less hassle, while resisting contact with toxic liquids
Neck protector
It works as a layer that protects the neck from toxic substances for the skin and also from radiation.
