ABSTRACT:
Silica aerogels which exhibit very little shrinkage or partial growth during processing and drying are produced by foaming and reacting a mixture of an oxidated silicon compound, a salt forming compound and a gas in an aqueous medium. The foamed silica gel is then dried to remove water thereby producing silica aerogel.
The silica aerogels may be used as a thermal and sound insulator, filler, catalyst, catalyst carrier, reinforcing agent, binder, absorbent, thickening agent and may have other uses.
