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.

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.

Vermiculite is a kind of clay mineral similar to montmorillonite. It is a layered silicate. It is generally formed by hydrothermal alteration or weathering of biotite. It sometimes appears in the form of thick biotite (which is the biotite illusion of vermiculite), and sometimes in the form of soil. When vermiculite is heated to 300â??, it expands 20 times and bends. Vermiculite is a bit like a leech, hence its name. Vermiculite is generally brown, yellow, dark green, with an oily sheen, turning gray when heated.
After roasting at high temperature, the volume of vermiculite slices can rapidly expand 6-20 times, and the specific gravity after expansion is 60-180kg/m3, which has strong thermal insulation performance.
Our customers in Taiwan, China, who specialize in wholesaling horticulture and refractory materials, recently acquired expanded vermiculite from our inventory.
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.

Vermiculite is a hydrated magnesium aluminum silicate mineral with the formula, (Mg,Fe+2,Fe+3)3[(Al,Si)4O10](OH)2 4H2O. It undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite can withstand up to 1200 degrees Celsius. It is an excellent thermal and acoustic insulator, capable of retaining moisture for a longer time. It had a neutral pH of 7, thereby doesn�??t react with any compounds or materials.

Introduction of natural vermiculite wallpaper
Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature. It is a relatively rare mineral and belongs to silicate. Its crystal structure is monoclinic, which looks like mica from its appearance. Vermiculite is produced when certain granite is hydrated. It is generally produced at the same time as asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on soil nutrition. In 2000, the world's total output of vermiculite exceeded 500,000 tons. The main producing countries are China, South Africa, Australia, Zimbabwe and the United States.
Vermiculite wallpaper is a decorative material with fire-proof, heat-resistant and sound-proof effects. Vermiculite has the effects of fire prevention and heat insulation. Because of its natural characteristics, the living space created is a perfect combination of fashion and classicism, which fully reflects modern people's desire for green and environmental protection.
Vermiculite wallpaper, the product is mainly made of natural ore as raw material, based on non-woven paper base, and carefully crafted by professional designers after improvement. It completely eliminates harmful factors affecting health, so it is regarded as the most safe wallpaper . Among them, paper-based vermiculite is a new type of high-grade decorative material processed by scientific methods from natural ore. It is extremely elastic, visually impactful and soft to the touch. It is called "the best home decoration wallpaper"
Advantages of natural vermiculite wallpaper products: 1. Natural and environmentally friendly. 2. Fire and flame retardant. 3. Sound insulation and anti-noise. 4. Super texture.
