Ceric hydrogen phosphate gels possess a very unique spatial organization, being nearly amorphous materials with a fibrous structure. Using a sol-gel approach, we succeeded in preparing bulky gels containing as much as 20,000 molecules of water per cerium atom. Supercritical treatment of these gels made it possible to obtain the first ultralight monolithic noncarbonaceous aerogels with a density as low as 1 mg/cm 3 .
