Abstract
A glass foam and methods of producing the same are disclosed. The glass foam is produced from a dried glass precursor gel having nanometer-sized pores and a bulk amorphous oxide-based matrix with an inorganic network of primary constituent oxides. One method includes obtaining the dried glass precursor gel, heating the dried glass precursor gel to a temperature below the melting point of the gel, maintaining the temperature for a time sufficient to expand the dried glass precursor gel, and expanding the dried glass precursor gel to form the glass foam.
