Title: Inorganic matrix compositions, composites and process of making the same

Abstract: A modified alkali silicate composition for forming an inorganic network. The modified alkali silicate matrix is made by reacting an alkali silicate (or its precursors such as an alkali hydroxide, a SiO.sub.2 source and water), an acidic oxoanionic compound such as phosphoric acid, water and optionally one or more multivalent cation(s) selected from Groups 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16 of the periodic table such as an alkaline earth salt, water and optional processing aids. An inorganic matrix composite can be prepared by applying a slurry of the modified aqueous alkali silicate composition to a reinforcing medium and curing the composite at a temperature from about C. up to C. and a pressure of up to 20,000 psi for typical high-performance organic polymer processing (temperatures about C. to about C. and pressures <200 psi). The composite can be shaped by compression molding as well as other known fabrication methods.
