Vermiculite is a hydrous phyllosilicate 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 ...

As well as thermal methods, vermiculite may also be exfoliated chemically. By far the most effective chemical method known is that of using hydrogen peroxide (H 2 O 2).The exfoliating action of H 2 O 2 on particles of weathered mica was first noted independently by Drosdoff & Miles and Groves during soil particle size analyses procedures where H 2 O 2 was used to oxidize organic matter.
