Abstract

Magic‐angle spinning nuclear magnetic resonance (MASNMR) spectroscopy (²⁷Al) detected the coordination of Al in clays containing as little as 0.26% Al₂O₃. The ²⁹Si MASNMR of fluorphlogopite showed three distinct Si chemical environments which suggested short‐range ordering. Synthetic laponite and mica‐montmorillonite showed broad ²⁹Si resonances indicative of short‐range disorder. A saponite showed four ²⁹Si resonances. Considerable insight into the short‐range ordering of clays can be gained by ²⁷Al and ²⁹Si MASNMR.
