Abstract: The persistence of many seemingly metastable mineral assemblages in sediments and soils is commonly attributed to their sluggish transformation to the stable-phase assemblage. Although undou...
The reaction of gibbsite in various organic solvents at 250°–300°C under spontaneous vapor pressure of the solvents was examined. Glycols and aminoalcohols afforded the organic derivatives of boehmite...
Abstract: Gibbsite samples of various particle sizes (0.2?0 祄) were heated at 250癈 in a series of straight-chain primary alcohols under the autogenous vapor pressure of the alcohol (alcohothermal trea...
The solubilities of HCl-treated samples of corundum, gibbsite, boehmite, and diaspore in aqueous solutions at 298 K and one atmosphere pressure were determined from undersaturated and supersaturated i...
Abstract: The crystal structure of a deuterated synthetic boehmite powder, 兞-AlOOD, has been determined by time-of-flight neutron diffraction and Rietveld profile refinement in space group Cmcm to a w...
The adsorption of Cu2+ on microcrystalline gibbsite and boehmite from aqueous solutions having 2/1 and 5/1 glycine/Cu ratios has been studied using electron spin resonance (ESR). The presence of glyci...
The crystal structure of natural boehmite, AlOOH, from Tveidalen, Langesundsfjorden, Norway, with a = 3.693(1), b = 12.221(2) and c = 2.865(1) Å, was refined from single crystal X-ray diffractio...
Thirty two boehmites, synthesized at temperatures ranging from room temperature to 300°C were examined by scanning electron microscopy, transmission electron microscopy, electron diffraction, X-ray po...
The crystal structure of a synthetic boehmite sample has been refined to an R of 0.047 in the space group Amam from X-ray powder diffraction data. Inclusion of hydrogen atoms and/or refinement in the ...
Two mutually exclusive views exist concerning the relative stabilities of gibbsite and boehmite in soils. These are examined in terms of experimental and thermodynamic evidence and it is shown that al...
A model is presented for interpreting the observed nuclear spin relaxation of the protons in the water molecules of the dispersing phase in terms of the modification of molecular motion in the solid-l...
