| Abstract: | The temperature dependences for conductivities and 1H NMR relaxation times are reported for homionic (exchanged) montmorillonite clays. Ionic conductivity in the interlayer region is primarily protonic (H+), arising from the Brønsted acidity of hydrated interlayer cations. Hydrogens outside the hydration shell appear to undergo translation by chemical exchange. |
