- Vermiculite - Wikipedia
Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated Exfoliation occurs when the mineral is heated sufficiently; commercial furnaces can routinely produce this effect Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite [3]
- Vermiculit – Wikipedia
Vermiculit gehört zu den Tonmineralen, die durch ihre Ionenaustauschfähigkeit maßgeblich zur Bodenfruchtbarkeit beitragen Sie ähneln sowohl strukturell als auch von der Erscheinungsform den Glimmermineralen und bilden wie diese flockige Kristalle
