Signature material
Sepiolite.
A remarkable fibrous magnesium clay — and the mineral at the heart of Anker Mining Co. Supplied in granular and micronized grades to buyers around the world.
What is sepiolite?
A naturally fibrous clay with rare industrial versatility.
Sepiolite is a hydrous magnesium silicate distinguished by its needle-like fibrous crystal structure. That microstructure gives it an unusually high surface area and porosity — the source of its exceptional absorption and thickening behaviour.
Türkiye is one of the world's foremost sources of high-quality sepiolite, and Anker Mining Co. extracts it directly from reserves in the Eskişehir region — the same geology that has made Turkish sepiolite renowned for generations.
Key properties
Why industry values sepiolite.
Exceptional absorption
A high specific surface area and porous fibrous structure give sepiolite outstanding liquid and odour retention.
Rheological control
In liquid systems, sepiolite acts as a natural thickener and suspension stabilizer across a wide pH range.
Thermal & chemical stability
The mineral remains stable under heat and resists chemical breakdown, suiting demanding industrial processes.
Naturally sourced
Mined directly from our Anatolian reserves, processed mechanically with no aggressive chemical treatment.
