Can Pristina™ aerogels
function in bulk water without crumbling or dissolving ?
Yes; TAASI's Pristina™ Aerogel products are fully compatible with
bulk water applications and examples of these applications are given in
the technical applications section. For highly acidic or alkaline water
applications, dissolution may take place depending on the chemical structure
of the aerogel. In such applications, please consult with TAASI's technical
personnel before use.
Aerogels are typically
too fragile for industrial applications, did you overcome this problem
in Pristina™ aerogel products ?
Yes; TAASI has developed
aerogel products with high crush strength that meet or exceed industry's
requirements.
If aerogels are very light
(low density), they would require much larger volume equipment than currently
available in industry; how can this situation be resolved ?
TAASI has developed procedures for manufacturing higher density (up to
0.6 g/cc or more) aerogel products, which are compatible with currently
used industrial equipment.
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.
