CLAY MINERALS

Smectites form a large group of TOT layer minerals with both cations and water molecules between the layers. They may be either dioctahedral or trioctahedral and the net charge on the TOTlayers is the result of various substitutions in both tetrahedral and octahedral sheets (e.g. Al3+ for Si4+ in the tetrahedral sheets, or Mg2+ (or Fe2+) for Al3+ in the octahedral sheet.).

Effects of Layer

For clay minerals with negatively charged layers (i.e., high and low charge), the homogeneous nucleation of the CH₄ hydrate occurred away from the surface. For a clay mineral with a neutral-charge layer, the CH₄ hydrate could nucleate either in the bulk-like solution homogeneously or at the clay mineral–H₂O interface heterogeneously. Get price
