<p>A modified alkali silicate composition for forming an inorganic network is disclosed, wherein the composition is made by reacting an alkali silicate (or precursors such as an alkali hydroxide, a SiO2 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, 11, 12, 13, 14, 15 or 16 of the periodic table such as an alkaline earth salt, water and optional processing aids such as a clay filler. A composite can be prepared by applying the modified aqueous alkali silicate composition to a reinforcing medium and curing the composite at a temperature from 15 °C up to 1000 °C and a pressure of up to 20,000 psi (137.895 MPa), wherein the composite or neat resin components can exhibit excellent dimensional stability to 1000 °C and higher, and can be prepared at temperatures and pressures typical for organic polymer processing. The composite can be shaped by compression molding as well as other known fabrication methods.</p> |
