Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance.  

Vermiculite is basically a hydrated phlogopite mica which has the remarkable ability t expand to many times its original volume when heated at 850 °C.-1100°C.Vermiculite is most widely used in its exfoliated form. 

Exfoliated Vermiculite

The exfoliation process is carried out commercially by passing crude vermiculite through a furnace chamber in a controlled manner. The crude vermiculite then expands at right angles to the cleavage planes, producing concertina-shaped particles many times their original volume.Exfoliated vermiculite can be obtained from commercial exfoliators. If large quantities are required, the equipment needed to exfoliate vermiculite can be obtained from furnace manufacturers.
