x-Ray Studies on the Hydrous Oxides. V. Beta Ferric Oxide Monohydrate

The secondary iron oxidehydroxide mineralogy of some deep-sea and fossil manganese nodules: A Moessbauer and X-ray study.

“…It incorporates a small central channel (' 3.9A diameter) which, as previously mentioned, the chloride ions can occupy and stabilize the lattice (WEISER and MILLIGAN, 1935;MACKAY, 1960).…”

“…The formation of akaganeite on hydrolysis of iron (III) is favoured by the presence of chloride ions (MURPHY et al, 1975(MURPHY et al, , 1976, and it is commonly synthesized by the hydrolysis of iron (III) chloride (WEISER and MILLIGAN, 1935;MACKAY, 1960;FEITKNECHT et al, 1973FEITKNECHT et al, , 1975INOUYE et al, 1974;HowE and GALLAGHER, 1975). METSON (1977), however, showed that the extent of akagandite formation during the corrosion of mild steel plates in soils is not related to the chloride level of the soil, and required levels of only a few hundred ppm for its formation.…”

A Micro-Raman Spectroscopic Study of Marine Atmospheric Corrosion of Carbon Steel: The Effect of Akaganeite

“…38,39 It is believed that akaganeite comes from the oxidation of green rust GR1(Cl), [40][41][42] which is one of the initial rust phases in NaCl-induced marine atmospheric corrosion. 9,10 Sea salts that deposit on steel samples first initiate corrosion and then can be incorporated into the corrosion products.…”

Structures of β-FeOOH Particles Formed in the Presence of Ti(IV), Cr(III), and Cu(II) Ions

“…The colloidal particles of this material are easily prepared by hydrolysis of an aqueous FeCl 3 solution and have attracted attention in colloid science for a long time. Distinct from other ferric oxyhydroxides, the formation of β-FeOOH needs halogen ions such as Cl − and F − , which stabilize the tunnel structure of β-FeOOH crystals (2)(3)(4). Cl − ions in the tunnels of the crystals can be removed by washing with water, although the thermal stability is reduced (5).…”
