Exfoliated Vermiculite Vermiculite Product Details Vermiculite is a kind of natural, non-toxic, inorganic silicate mineral, whose raw ore looks like mica. Vermiculite is formed by the hydrothermal alteration or weathering of minerals, usually biotite and phlogopite. When heated, it expands like leech. Vermiculite are divided into raw vermiculite and expanded vermiculite by stages, and according to the color, it can be divided into golden vermiculite, silvery white vermiculite, milky white vermiculite. Exfoliated Vermiculite Vermiculite, with layer construction and interlaminar water. It begins expend when it is heated over 200??, becoming the worm-like shape and it can be 15-25times bigger than the original volume, maximum 30 time. when it is rapidly heated to 800??. This forms the material with low density (100-300kg/m), excellent insulation property and good hydroscopicity and ion exchange capacity.

In agriculture, vermiculite can be used as soil conditioner. It develops the soil permeability and water content, makes acidic soil change into neutral soil. Exfoliated vermiculite plays a very good heat insulating effect, making the building warm in winter and cool in summer. In gardening, vermiculite can be used for flowers, vegetables, fruit cultivation, breeding and other aspects.

Raw vermiculite: An inorganic, naturally occurring mineral with remarkable heat resistance and insulation properties. Lightweight and expandable: When heated, raw vermiculite expands, making it an ideal additive for construction materials. Fire-resistant: With a high melting point, it\'s an effective fireproofing material. Excellent moisture retention: Raw vermiculite\'s moisture-absorbing qualities make it valuable in horticulture and gardening. Natural insulation: Used for its insulating properties in the construction industry, it helps conserve energy and improve thermal performance.
General Description: Vermiculite {(Mg, Fe, Al)3(Al, Si)4O10(OH)2 - 4H2O, Hydrated Magnesium Iron Aluminum Silicate Hydroxide} is an important member of the Montmorillonite/Smectite Group, members of which also belong to the larger general group known as the Clays. Vermiculite is also sometimes placed in the Mica Group, although recent analysis has excluded it from this group. Vermiculite is basically overly hydrated biotite or phlogopite. Natural specimens originated as these minerals and later altered to vermiculite through weathering or hydrothermal processes. Vermiculite typically forms small platy mica like crystals. These crystals contain water in their structures and when heated to above 870C, the water turns into steam causing the crystals to expand rapidly. The volume increase can be 2000 to even 3000%. Appearance: Flakes or powder Applications Vermiculite is very useful for many industrial purposes. It is very lightweight, chemically non-reactive, fire resistant and odorless. Vermiculite can be used to soak up such toxic liquids as fertilizers, herbicides and insecticides. It is this ability that is also being put to good use as a bedding for pets and livestock. In addition, vermiculite can be used in concrete and ceramics as a heat resistant additive. Important Properties Vermiculite is usually brown to golden brown, also white, colorless or yellow. Luster is pearly to greasy. Its Crystals are translucent and Crystal System is monoclinic; 2/m. Its Crystal Habits include pseudohexagonal tabular crystals or "books", also found in compact or lamellar masses or microscopic crystals. The Cleavage is perfect in one direction, basal. Fracture is uneven to lamellar. The Hardness is 1.5 (can sometimes leave marks on paper). The Specific Gravity is 2.3 (below average). Its crystals expand to many times their original volume when heated. Best Field Indicators are softness, color, luster and expandability when heated.
