    The influence of silicate content on thermal stability of 2-line ferrihydrite and properties of its transformation products
    (Wydawnictwa AGH, 2014) Pieczara, Gabriela; Rzepa, Grzegorz; Gaweł, Adam
    Naturally occurring ferrihydrite ($Fe_{5}HO_{8} \cdot 4H_{2}O$) is a poorly ordered iron (oxyhydr)oxide mineral, with non-stoichiometric composition and not fully understood structure. Because of its unique chemical and physical properties, such as low crystallinity, high surface area and surface reactivity, ferrihydrite plays significant role in e.g. inorganic weathering processes, biochemical cycling of iron and as a sorbent in various near-surface environments.
