Synthesis of micro-mesoporous glass-analcime composite structure with soda–lime–silica glass as raw material

Abstract

The micro-mesoporous composite phase structure of the analcime and the glass phase was successfully synthesized at 200∘C by using hydrothermal method, in which the soda–lime–silica glass was used as the silica source and the sodium hydroxide and aluminum oxide were used as additive. The TEM and SEM results showed that the obtained rod-shaped analcime was growing on the surface of glass particles. Thermogravimetric analysis indicated that they are stable and the adsorption isotherm shape indicated the coexistence of micropores and mesopores.
