“…9 we have plotted log tr versus log × II~bbsite. The supersaturations with respect to gibbsite were calculated from published data by different investigators (9)(10)(11)(12). The results of some experiments at 62.5 and 90°C are also included in this figure.…”

“…Ageing of metal hydroxides may proceed either to a metastable "inactive" form of the same phase, or by phase transformation to a more stable modification. Feitknecht and Schindler (1963) indicated that amorphous ferric hydroxide may be modified to the active form of goethite or to hematite, the thermodynamically stable c~ phase. Because of the very fine particle size (and hence large surface area/volume ratio) the dominant control of the stabilities of the different mineralogical phases is probably the free surface energy of the particle (Ferrier, 1966).…”

Abstract--Fe 57 Mfssbauer spectroscopy has been used to determine the nature of iron-containing minerals in Lower Greensand samples from an experimental lysimeter at Uffington, Oxfordshire, both before and after a three-year irrigation with a synthetic heavy metal leachate. Analysis of the spectra measured at 300 ~ 77 ~ and 4.2~ and at 4.2~ in an applied field of 45 kOe shows that iron is present in the uncontaminated sandstone in fine-grained goethite (a-FeOOH) and glauconite. In the irrigated samples iron is precipitated as a fine-grained ferric hydroxide gel having values for the hyperfine field at 4.2~ of 435 and 470 kOe. The stability of the gel over the three-year period of irrigation may be explained by surface energy considerations.

“…The diffusion coefficient of Al(OH) 4 -was reported by Heusler and Allgaier to be 8.4 x 10 -6 cm 2 /s (11). C s was taken as 0.05 M, the solubility of gibbsite, the least soluble form of Al(OH) 3 and normally the first precipitate from aqueous solution (13,14). With these values, t p from Eq.…”

Surface Processes Accompanying Corrosion-Induced Hydrogen Absorption into Aluminum

The role of hydrogen-containing species in the alkaline dissolution of aluminum was studied by secondary ion mass spectrometry (SLMS). Large number densities of submicron particles nucleated and then disappeared during dissolution, at intervals of approximately 3 min. The particles were composed of aluminum hydride, with an aluminum hydroxide surface layer. When particles first appeared, the aluminate ion concentration near the surface was at the solubility of Al(OH)3, and the potential was close to the Nernst potential for oxidation of AlH3 to Al(OH)3. The observed formation of AlH3 indicates that the dissolving Al surface was poised near this equilibrium potential, i. e. that a hydride species serves as an intermediate in the dissolution process.Keywords alkaline dissolution, aluminum hydrides, hydrogen absorption, ion concentrations, surface processing, corrosion, high performance liquid chromatography, aluminum Disciplines Biochemical and Biomolecular Engineering | Biology and Biomimetic Materials CommentsThe archival version of this work was published in S.
