Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Large commercial vermiculite mines currently exist in the United States of America, Russia, South Africa, China, and Brazil.
Vermiculite is a naturally occurring hydrated magnesium-aluminum-iron silicate mineral, structurally similar to mica, that undergoes dramatic expansion when heated. During this "exfoliation" process, raw flakes expand 8 to 30 times their original volume into lightweight, accordion-like particles. It is known for being sterile, odorless, pH-neutral, and highly absorbent, holding water and essential nutrients for plants, making it a popular horticultural potting amendment. Beyond agriculture, its excellent fire resistance and thermal insulation properties render it useful in construction materials, such as fireproof plaster, lightweight concrete, and roof insulation. It is also employed as a packing material for transporting hazardous liquids. Its unique properties make it a valuable, long-lasting component in various eco-friendly and agricultural applications.
