TLDR
In this article, the authors examined some of the factors affecting the crystallised phase of aluminium hydroxides in highly caustic solutions using several different methodologies, and concluded that the results of these results were not necessarily indicative of the in situ crystalline components.About:

The aluminum chemistry and corrosion in alkaline solutions
TL;DR: In this article, a thorough knowledge of the chemistry of aluminum and susceptibility to corrosion in alkaline solutions is reviewed and a review of phase transitions with aging time and change of environment is also performed.
Journal ArticleDOI
In Situ Studies of the Sol−Gel Synthesis of Materials
TL;DR: In this article, the use of in situ methods to study the synthesis of materials from sol−gel precursors is reviewed, with particular emphasis on the formation of crystalline phases from solid gel precurors and the crystallization of zeolitic materials from solution under hydrothermal conditions.

The crystallization mechanism of Al(OH)3 from sodium aluminate solutions
TL;DR: Particle size distribution analysis of dynamic light scattering (DLS) in the particle size range of 0.05-1.0μm shows that in a solution of intermediate concentration (i.e. 1.50-M NaOH, 0.97-M Al(III)) progressive, uni-modal nuclei growth occurs up to an average diameter (d ) of ≈300-nm as discussed by the authors.

Microstructure and corrosion performance of Al-32%Co alloys
TL;DR: Al-32 (wt%)Co alloys have been prepared by casting, arc melting under argon and free sintering, and the received microstructures have been explained in terms of solidification sequences and solid state diffusion processes as discussed by the authors.

Surface and structural characteristics of gibbsite precepitated from pure, synthetic Bayer liquor
TL;DR: In this paper, the ex situ surface and structural characteristics of gibbsite precipitated from pure, synthetic, supersaturated caustic aluminate solutions were examined by various techniques to determine the presence of an amorphous aluminium hydroxide phase which might be linked with the crystal growth process.

Refinement of the crystal structure of gibbsite, Al(OH)3
H. Saalfeld,M. Wedde +1 more
TL;DR: In this article, the structure determination by MEGAW (1934) was confirmed and the revised interatomic distances as well as the hydrogen positions were reported, based on diffraotometer data the struoture of gibbsite has been refined by least squares oalculations.
