Sepiolite Nanomaterials: Structure, Properties and Functional ...
Sepiolite is a natural magnesiumrich hydrous silicate clay mineral with fibrous crystal morphology (Fig. A).The ideal structural formula of sepiolite is Si 12 O 30 Mg 8 (OH) 4 (OH 2) 4 ·nH 2 O, as proposed independently by Nagy and Bradley [1] and Brauner and Preisinger [30].According to them, the crystalline lattice of sepiolite was composed of silicon‑oxygen tetrahedral sheets and ...
