High-Pressure Raman and X-Ray Scattering Studies on Vermiculite Layered-Silicate Intercalation Compounds.

Pressure-Induced Intercalation of Alcohol Molecules into a Layered Titanate

“…have reported that some graphite intercalation compounds (GICs) were synthesized on compression of graphite with alkali or lanthanide metals. Wada et al have claimed that HP promoted the intercalation of water molecules into clay minerals such as kaolinite and Na-vermiculite. However, these GICs and clay complexes had been prepared even without HP. − That is to say, no intercalation reaction which was driven exclusively by HP conditions has been reported for layered compounds …”
