Abstract
An inorganic foam formed by initially mixing particulate aluminum with an aqueous solution of an alkali metal base for a time sufficient to at least initially cause the formation of hydrogen gases therefrom, folding the mixture into an aqueous alkali metal silicate solution in a manner to substantially retain concentrated areas of the mixture in the silicate solution for a time sufficient to allow a substantial amount of the theoretical hydrogen gas to form, then thoroughly mixing the materials to form a solid inorganic foam.
