    Vermiculite is a mineraloid of hydrated laminar magnesium-aluminum-iron silicate.
    Its chemical composition greatly varies and chemical formation could be simplified
    as Mgx(H2O){Mg3-x[AlSiO3O10](OH)2}. When heated to a temperature of about 850-950C,it instantly expands(exfoliates) up to 15-25 times as water flashing into
    steam, maximum 30 times its original bulk volume. There is a color change during
    expansion from golden brown into silver white depending upon the composition of
    the vermiculite and temperature. With such prominent characteristics as being
    fireproof, heat insulating, sound and moisture absorbing, non-toxic, lightweight
    and disease free, it is widely used in construction, chemical industry, petroleum,
    electronics, light industry, environmental protection and as a medium of agricultural
    chemical products etc.
