Abstract

The environment of the Al and Si atoms of diphasic and single‐phase aluminosilicate gels was determined by solid‐state 27Al and 29Si magic‐angle spinning nuclear magnetic resonance (MASNMR) spectroscopy, The tetrahedral coordination of Al increased with decreasing Al/Si ratio in single‐phase gels but not in diphasic gels. The results showed that ultrahomogeneous mixing on a next‐nearest‐neighbor level is achieved in single‐phase aluminosilicate gels, while in diphasic gels this has successfully been avoided.
