Sepiyolit, also known as Meerschaum, is a hydrated magnesium silicate mineral with a unique fibrous and porous structure. It is primarily found in Turkey and Spain, making it a rare and valuable industrial mineral2.

Properties

• Chemical Formula: Mg₄Si₆O₁₅(OH)₂·6H₂O

• Density: 2.0–2.3 g/cm³

• Color: White, gray, yellow, pink (varies due to impurities)

• Structure: Fibrous, lightweight, and highly porous

• Absorption Capacity: Excellent moisture and oil absorption

Uses

• Filtration & Absorption → Used in water purification, oil spill cleanup, and cat litter.

• Industrial Applications → Found in paints, coatings, plastics, and ceramics to enhance properties.

• Agriculture → Acts as a soil conditioner to improve water retention.

• Art & Craft → Historically used for pipe carving and sculptures due to its softness.

• Construction → Applied in lightweight building materials for insulation.

Sepiyolit’s high thermal stability makes it suitable for high-temperature applications, and its porous nature allows it to be used in filtration and adsorption processes

Sepiyolit is known by several alternative names, including:

• Meerschaum (German origin, meaning "sea foam")

• Hydrated Magnesium Silicate

• Sepiolite Clay

• Lületaşı (Turkish name)

• Palygorskite-Sepiolite Group Mineral

• The CAS number for Sepiolite is 63800-37-3
