Vermiculite is a hydrous phyllosilie mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Large commercial vermiculite mines currently exist in the United States, Russia, South ...

Similarly to montmorillonite, vermiculite is a 2:1 phyllosilie, in which the negatively charged aluminosilie layer is composed of one octahedral sheet sandwiched between two tetrahedral sheets [36,37]. An interesting property of vermiculite is its exfoliation at higher temperatures, due to the loss of water in its interlayers .
