Atomistic Modeling of Gibbsite: Cation Incorporation
The Journal of Physical Chemistry B, 2001Computer modeling techniques provide a useful mechanism with which to model the morphology of defect crystals. In this work, a study of the incorporation of sodium and potassium cations into the morphologically important surfaces of gibbsite was conducted.

Electrorheological properties of mechanically activated gibbsite
International Journal of Inorganic Materials, 2001Abstract Change in the surface state during milling of gibbsite (GB) is elucidated by electrorheological properties of the suspension comprising GB and silicone oil. Under dc electrical field up to 2 kV/mm, milling brings about remarkable increase in the yield stress, e.g., milling GB for 3 h increases 100 times the yield stress at 2 kV/mm. Amount of

Transformation behavior of gibbsite to boehmite by steam-assisted synthesis
Journal of Solid State Chemistry, 2018Conversion of gibbsite to boehmite as a precursor for many aluminum oxide materials was widely concerned. Herein, the steam-assisted crystallization (SAC) method was conducted to synthesis the boehmite from gibbsite.

Thermal decomposition of mechanically activated gibbsite
Thermochimica Acta, 1999Abstract Gibbsite (AlOH)3 was mechanically activated by grinding for 20 h, and the changes in its structure were studied by thermal analysis, X-ray powder diffraction and 27 Al MAS NMR. Grinding caused the rupture of a significant proportion of the Al–OH bonds, but the resulting molecular water was immediately adsorbed on to the activated ...

Sedimentary Geology, 2018
The terrestrial deposition process for karst bauxite is difficult to constrain due to its allochthonous origin, multiple controls and the difficulty in geodynamic reconstruction.

A Gibbsite-Cemented Quartz Sandstone
SEPM Journal of Sedimentary Research, 1984ABSTRACT A gibbsite-containing quartz sandstone occurs near Fort Walton, Florida. Scanning electron micrographs show the gibbsite of the matrix to be anhedral which is the typical morphology in many deposits of bauxite. At the contact surface with the quartz grains, however, the gibbsite crystals are euhedral, as if recrystallized from solution.

Gibbsite in the weathered dartmoor granite
Geoderma, 1971Abstract Gibbsite encountered in the weathered Dartmoor granite is an initial product of the weathering process; its occurrence is not indicative of an earlier humid tropical environment.

ANION ADSORPTION BY GOETHITE AND GIBBSITE
Journal of Soil Science, 1972Summary The relationship between adsorption and pH, termed the adsorption envelope, varies with the p K a, of the conjugate acid of the anion, for several adsorbents in presence of an excess of specifically adsorbed anions.
