What is the difference between aerogel and xerogel?
What is the difference between aerogel and xerogel?
When the liquid from the gel is evaporated at room temperature, the solid gels left behind are called xerogels. Whereas when the liquid from the gel is extracted at supercritical state of liquid, these materials are called aerogels.
How is xerogel made?
Aerogels are among the lightest solid materials known to man. They are created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air. The silica is combined with a solvent to create a gel. This gel is then subjected to supercritical fluid extraction.
What company owns aerogel?
Aspen won’t be the only public company manufacturing aerogels–Cabot Corporation (NYSE:CBT) also manufactures aerogel materials in both particle and insulating blanket form.
What is meant by xerogel?
Definition of xerogel : a solid formed from a gel by drying with unhindered shrinkage — compare aerogel.
What is xerogel used for?
SiO(2) xerogels are potential biomaterials to be used as matrix materials for the extended and controlled release of different kinds of biologically active agents administered by various routes.
Why was aerogel created?
Aerogels can be made from a variety of chemical compounds. Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in “jellies” with gas without causing shrinkage….Metal oxide.

Is aerogel a good electrical insulator?
Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. (Silica aerogel is an especially good insulator because silica is also a poor conductor of heat; a metallic or carbon aerogel, on the other hand, would be less effective.)
Who invented aerogel?
Samuel Stephens Kistler
Samuel Stephens Kistler, the inventor of aerogel. It is a great story and details the origins of aerogel. In it you will discover that aerogel was invented some time between 1929 and 1930, believe it or not, and was first commercialized as early as the 1950’s.
