In addition to a-FeOOH, (/8, y, 8)-FeOOH have been synthesized. The last varieties apparently are metastable and convert to hematite a-Fe203 when boiled, with a-FeOOH formed as an intermediate phase (Butler and Ison, 1965). All the other mineral species (limonite, turgite, hydrogoethite) are goethite with a variable amount of adsorbed water, or mixtures of goethite, amorphous iron hydroxides, and sometimes hematite. [Pg.274]

Then, they prepared the catalysts using ruthenium carbonyl [22]. They found that for two iron oxides (a- and 8-FeOOH) the reaction rate constants are considerably higher than those of reactions with other catalysts based on RuCla. [Pg.28]

Feroxyhyte (8-FeOOH) occurs naturally in soils in poorly crystallised (disordered) form, but is more common as a synthetic phase, belonging to the hexagonal system (Cornell and Schwertmann, 1996). Natural feroxyhytes occur above weathered basalts and have so far only been identified on Hawaii (Parfitt et al, 1988). Synthetic feroxyhyte may be produced by titrating iron(II) chloride with sodium hydroxide and water (Schwertmann and Cornell, 2000). Identifications in works of art are not yet known. [Pg.156]
