    MAIN INFO

    The layered structure silicate mineral of the orbital Orthogonal ( orthorhombic) crystal system, D62h-Pncn; the unit cell parameters are a0=1.34nm, b0=2.68nm, c0=0.528nm; the chemical composition is Mg4Si6O15(OH) 2·6H2O consists of a silicon tetrahedron and a magnesia octahedron. The oxygen constituting the siloxane tetrahedron base constitutes a continuous crystal layer spaced apart by about 0.65 nm, and the apex oxygen is alternately directed upward and downward of the continuous crystal layer. The tetrahedrons pointing in the same direction are connected to each other to form two pyroxene chains. The two pyroxene chains are connected to form an amphibole chain, and the crystal layer formed by the apex angles of the tetrahedrons can be perfected by hydroxyl groups. These crystal layers are interconnected by octahedral coordinated magnesium ions.

     

    Characteristics

    Sepiolite is opaque and off-white, grey or cream color, breaking with a conchoidal or fine earthy fracture, and occasionally fibrous in texture.Due to the fact it can be readily scratched with the finger nail, its hardness is ranked at about 2 on the Mohs scale.The specific gravity varies from 0.988 to 1.279, but the porosity of the mineral may lead to error. Sepiolite is a hydrous magnesium silicatehaving the chemical formula Mg4Si6O15(OH)2·6H2O.

    When first extracted, sepiolite is soft. However, it hardens on exposure to solar heat or when dried in a warm room.

     

    About Sepiolite

    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.

    Name: Named in 1847 by Ernst Friedrich Glocker from the Greek, "sepion," cuttle-fish bone, because of its low density and porous, bone like appearance. Originally named meerschaum by Abrahan Gottlieb Werner in 1788. Later translated as l'Ecume de mer. In 1794, the mineral was called keffekill by Richard Kirwan. Alexandre Brongniart called this mineral magnesite in 1807.

    Why was sepiolite recommended for water treatment

    Due to its strong adsorption, it is commonly used in industry to treat industrial wastewater, including heavy metal wastewater and organic wastewater. Among them, the sepiolite is sometimes modified: after the modified sepiolite, the network pore size becomes larger, and more acidic base groups are exposed on the surface, and these light bases and water molecules can be complexed with heavy metal ions. At the same time, during the adsorption process, the heavy metal ions undergo ion exchange reaction with the exchangeable cations in the modified sepiolite, further reducing the content of metal ions in water. Not only that, sepiolite can absorb water to its own 2-2.5 times weight, so it can be used as a humidity-controlling functional material to balance and regulate the content of atmospheric water in a certain range, so as to maintain a certain humidity. At present, the prepared sepiolite humidity control material can reach: the maximum moisture absorption can reach 0.7400 g/g, and the maximum moisture release amount can reach 0.6886 g/g. Nowadays, it is also made into a catalyst carrier by utilizing its adsorption property to improve the production efficiency of industrial production.
