1 Brief Introduction :


Vermiculite is a kind of layer structure of magnesium aluminum silicate secondary water metamorphic minerals, ore outside like mica, usually by black mica (gold) by the weathering of hydrothermal alteration effect or, it is because of the hot water expands flexure, form resembles leeches, therefore calls vermiculite.


Vermiculite, chemical formula M g × (H2O) [Mg3 × (AlSiO3O10) (H2O)], is a magnesium water inclouded aluminum silicate secondary metamorphic minerals of layered structure. It likes mica in form, and usually come from weathered or hydrothermal alterated black (gold ) Mica. It will present a deflection shape after heat expansion and water loss, liking a leech pattern in form , so it gets the name vermiculite

4 Material Composition

Vermiculite is a natural, non-toxic mineral, swells of minerals under high temperature. It is a very rare mineral, belongs to the silicate. Its crystal structure is monoclinic system, from the appearance it looks like mica. Vermiculite is a granite hydration. It generally comes with asbestos. Because of vermiculite with ion exchange capacity, it is of great effect on soil nutrition.
