Abstract
Provided are ceramic foams. The ceramic foams may have a hierarchical pore gradient. The ceramic foams may be silica aerogels. The ceramic foams may be made by reaction of one or more precursors in the presence of an inert gas generated by a pore-forming gas-forming additive. The ceramic foams may be used as insulating materials.
Claims11
A method for forming a ceramic aerogel comprising:
- contacting
- a ceramic precursor;
- a pore-forming gas-forming additive selected from urea and a combination of sodium bicarbonate and urea;
- a catalyst;
- and
- a surfactant,
- wherein the contacting results in formation of an inert gas and a ceramic aerogel having a pore gradient structure.
