What about the thermal stability of Pristina aerogels in high temperature applications ?
Thermal stability in terms of maintaining the same porosity, specific surface area, and chemical structure in high temperature applications depend on the chemical nature of the aerogel. For example, a metal oxide aerogel might not change its chemical composition on exposure to a high temperature (i.e. does not burn), but its porosity and surface area might be severely decreased on prolonged exposure to temperatures above its sintering temperature. Thus for a particular high temperature application, an aerogel with a metal oxide having a higher sintering temperature than the application’s temperature should be selected. Please consult with TAASI’s technical personnel for your particular application.
