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.
