Vermiculite
Vermiculite is a term applied commercially to micaceous minerals
(essentially hydrated silicates of Al, Mg and Fe), usually
alteration products of biotite or phlogopite micas, formed by the
removal of much alkalies and addition of water. Vermiculite differs
from mica in its characteristic property, i.e., exfoliation. Crude
vermiculite is mostly exfoliated before use. In order to convert
raw vermiculite into a product suitable for industrial use, it must
be exfoliated or expanded by heating, a process termed
'exfoliation'.
Uses
Horticultural Vermiculite is known for its
horticultural applications. It is a common component in potting
soils. Unfoliated (unexpanded) vermiculite has only minor uses,
such as for circulation in drilling muds and in the annealing of
steel.
Insulation Vermiculite is chemically inert,
fireproof, nonconductor of electricity and a good insulator against
heat (both radiant and conducted), cold and sound. Unlike cork and
other organic light weight insulating material, it does not rot and
is not attacked by vermin and has a fair mechanical strength.
Carrier It is also used as a carrier in
fertilizers, herbicides and insecticides.

Binding Agent Cementing mixtures of exfoliated
vermiculite and binding agents such as gypsum and plaster, have
been important products and are applied to structural steel members
in commercial buildings.
Fireproof Plaster/ Refractory Board The mineral is
used in various types of building boards. Fine-sized, untreated
vermiculite concentrates are included in the preparation of
fireproof plaster boards. The exfoliated product forms the basis of
some light weight plasterboard, whilst ground, exfoliated
vermiculite is used in various refractory board products. The
principal uses of expanded vermiculite are based on its thermal
insulating quality (due to presence of innumerable air cells),
low-density, fireproof nature and granular form.
Thermal Insulation Larger vermiculite granules are
used as a loose fill for thermal insulation for homes, industrial
structures, cold storage, refrigeration and high temperature and
low temperature industrial equipment. The high absorbency and
chemical inertness of exfoliated vermiculite have made it suitable
for a wide range of absorbent packing materials as well as for
packaged units for the spill containment of oil and similar
liquids.
