  • Sepiolite Nanomaterials: Structure, Properties and Functional . . .
    Sepiolite, together with palygorskite, is an end-member of the palygorskite sepiolite polysomatic series The name sepiolite was first used by Glocker [12] and was derived from the Greek term for cuttlefish, which is as light and porous as the mineral itself Another term still used for sepiolite is Meerschaum, which was coined by Kirwan [13]
  • From old to new inorganic materials for advanced applications: The . . .
    Aluminum-exchanged sepiolite by hydrothermal processes in alkaline medium developed by TOLSA S A is an example of resulting sepiolite-based materials showing elevated cation exchange capacity and high surface acidity, useful in applications as for example fluid catalytic cracking (FCC) processes (Álvarez et al , 2011)
  • Sepiolite clay: A review of its applications to immobilize toxic metals . . .
    Sepiolite is derived from Greek words sepia and lithos, which denotes cuttlefish stone As depicted by name (foam of sea), the sepiolite can float on water owing to its low specific gravity and high surface area Sepiolite is a naturally-occurring clay mineral which is widely found in soils and sediments
  • Sepiolite - an overview | ScienceDirect Topics
    Sepiolite is a silicate clay first used as a lubricant for ground diets and as a pelleting agent [149, 150] The use of sepiolite was found to increase feed consumption and feed:gain ratios in pigs and broilers [151] The effects appear to be related to changes in digesta viscosity as well as microbial activity
  • Unlocking the potential of sepiolite: Designing high-performance energy . . .
    Sepiolite is a layered silicate clay with the ideal molecular formula Si 12 O 30 Mg 8 (OH) 4 (H 2 O) 4 ·8H 2 O [8] As shown in Fig 1, Sepiolite is composed of two layers of silicon-oxygen tetrahedra and a layer of magnesium-oxygen octahedra [9]
  • Sepiolite - an overview | ScienceDirect Topics
    Sepiolite is most commonly found as a result of the former process, whereas palygorskite is often characterized as a product of the latter Thus, sepiolite typically occurs in lacustrine, often saline, strata, while palygorskite is commonly found in conjunction with soils, alluvium, or most abundantly, calcretes
  • New insight into the phase transformation of sepiolite upon alkali . . .
    In sepiolite, whose Si-based layer is composed of periodically inverted tetrahedral strips, the Si-O-Si bond angle at the ribbon joints equals 180 °C High bond order renders the Si O bonds in these bridges particularly strong, as indicated by the high FTIR wavenumber of the corresponding stretch (1210 cm −1) As a result, the areas of the
  • Mechanical and thermal properties of sepiolite strengthened . . .
    Sepiolite is a microcrystalline hydrated magnesium silicate with Si 12 Mg 8 O 30 (OH,F) 4 (H 2 O) 4 ·8H 2 O unit formula Sepiolite shows unique characteristics over various types of fillers It has a unique needle-like sinewy structure that liberates when dispersed in water or other polar dissolvable, outlining a monomer fibre or miniature
  • Sepiolite: A new component suitable for 380 km h high-speed rail brake . . .
    Interestingly, the addition of sepiolite causes a change in the traditional saddle-shaped friction curve due to high temperature lubrication Meanwhile, the primary advantage of sepiolite lies in its superior abrasion resistance, evident in the increased friction coefficient and altered wear mechanisms with higher sepiolite content
  • Sepiolite: Properties and Uses - ScienceDirect
    Sepiolite and zeolite, highly porous minerals, are becoming widely used as alternative materials in areas where sorptive, catalytic and rheological applications are required High ion exchange capacity and high surface areas and more importantly their relatively cheap prices make them attractive adsorbents
