Vermiculite an overview ScienceDirect Topics

Production, Origin, and General Information—The raw material for vermiculite is a natural clay mineral that has a layered structure with water in between the layers. Expanded vermiculite is produced in a similar fashion as perlite by heating the grinded and sieved material to 1000°C. The water is converted to vapor at high temperatures in the oven, which increases interlayer spacing. This

Vermiculite Statistics and Information USGS

Vermiculite Statistics and Information. Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion-like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is
