Background

Vermiculite is a natural, inorganic, non-toxic mineral substance, which expands under the action of high temperature. It is a rare mineral and belongs to silicate. Its crystal structure is monoclinic, and looks like mica in its appearance. Vermiculite is produced when certain granites are hydrated. It is generally produced simultaneously with asbestos. Because vermiculite has ion exchange capacity, it has great effect on soil nutrition. Vermiculite is a clay mineral similar to montmorillonite, and is a silicate with a layered structure. Typically formed from biotite upon hydrothermal alteration or weathering. It sometimes appears as coarse biotite (which is the biotite artifact of vermiculite) and sometimes becomes fine to soil. When vermiculite is heated to 300 ℃, it can expand 20 times and bend. Vermiculite is somewhat like leech (commonly called leech) and so it has so a name. Vermiculite is generally brown, yellow, dark green, has the same gloss as oil, and turns gray after being heated. The vermiculite can be used as building materials, adsorbents, fireproof insulating materials, mechanical lubricants, soil conditioners and the like, and has wide application.
