company with operations in South Carolina did not expect to produce vermiculite in 2022. Data for U.S. exports and imports of vermiculite were combined with data for other mineral products by the U.S. Census Bureau. U.S. imports were estimated to be about 30,000 tons in 2022, a decrease which could be related to disruptions in the global supply

Huggett, in Reference Module in Earth Systems and Environmental Sciences, 2015 Clays (Vermiculite) (2:1) The second group of clays with exchangeable cations is vermiculite.Vermiculite has a talc-like structure in which some Fe 3 + has been substituted for Mg 2 + and some Al 3 + for Si 4 +, with the resulting charge balanced by hydrated interlayer …
The term vermiculite applies to a group of minerals characterized by their ability to expand into long, worm-like strands when heated. This expansion process is called exfoliation. The name vermiculite is derived from a combination of the Latin word vermiculare meaning "to breed worms," and the English suffix-ite, meaning mineral or rock.
The natural minerals of the Tebinbulak deposit, which are used as heat-insulation materials, were investigated. Their expansion coefficient depends on the raw grain size and ranges from 3.47 to 7.67. The structure of the material was studied by means of x-ray diffraction and infrared spectroscopy. The chemical composition was determined by the microprobe …

Vermiculite, a hydrated magnesium-aluminum-iron silicate mineral, has a range of uses that take advantage of its fire resistance, good insulating properties, high liquid absorption capacity, inertness and low density. Most applications for vermiculite use an exfoliated (heat-expanded) form of the mineral. In general, coarser grades of vermiculite are used as loose …
