The 29Si spectra indicate that Al-O-Al avoidance occurs on tetrahedral sites with considerable short-range order in accordance with the Homogeneous Dispersion of Charges (HDC) model of Herrero et al. (1985a), in which charge imbalance within the tetrahedral sheets is minimized. The 1H MAS NMR spectra indicate that every [6]Al is surrounded by six Mg octahedra. This content is PDF only.
