sepiolite, (German: "sea-"), a fibrous hydrated magnesium silicate, Mg 4 Si 6 O 15 (OH) 2 ·6H 2 O, that is opaque and white, grey, or cream in colour. It may resemble the bones of the cuttlefish Sepia, from which the name derives. In the Black Sea region, where the light, porous clay mineral is abundant, it is said to resemble sea-, hence the German name.

In this paper, a new type of porous ceramics was prepared using the raw sepiolite mineral. The porous ceramics was shaped by the dry pressing method and sintered in the range of 700 ~ 1200 °C.
Sepiolite Powder, also known as meerschaum or hydrous magnesium silicate, is a naturally occurring mineral that has a variety of uses in the construction and other industries. Its unique physical and chemical properties make it a versatile material for numerous applications. Here are some of the common uses and applications of sepiolite powder:
Sepiolite is a fibrous hydrous magnesium silicate clay mineral with a chemical formula, H6Mg8Si12O30H106H2O. It is a soft, porous, lightweight clay with non-swelling properties …
Sepiolite also acts as an opacifier and a colourant-carrier in various beauty products. Further, sepiolite's absorptive properties support formulations meant to absorb facial oils in darker complected women without affecting the matte finish and colour of the beauty product. Then too, sepiolite's adsorptive properties support formulations that ...
Activation Processes (Thermal or Physical) Harry Marsh, Francisco Rodríguez-Reinoso, in Activated Carbon, 2006. 5.9.14 The Year 2001: Carbon-sepiolite Pellets. Sepiolite is a fibrous silicate, Si 12 Mg 8 O 30 (OH) 4 (H 2 O))4, made up of microporous channels parallel to the fiber axis. The chemical composition and structure of sepiolite are responsible for good adsorbent …
Commonly found as compact masses of microscopic needles resulting in a low-density masses. May be an important constituent of "mountain leather". Free-standing acicular crystals not found in many localities. May be confused with palygorskite.
Sepiolite is a hydrous magnesium silicate formed by precipitation of near-surface brackish or saline waters, under semi-arid climatic conditions. Four major influences on the distribution of …

Sepiolite happens in clay regions like those produced by ice age glacial activity from orogeny. If there are great lakes with high clay contents, and a specific type of volcano deposits a lot of magnesium enriched ash into the lakes, the clay and the magnesium can dissolve and precipitate into high quantites of sepiolite precursor.
To evaluate the potential of sepiolite-based materials to resolve environmental pollution problems, a study is needed which looks at the whole life cycle of material application, including the residual value of material classified as waste from the exploitation of sepiolite deposits in the region or from its processing and purification.
