Preparation and properties of fibrous boehmite sol and its application for thin porous membrane

Preparation of γ-Al2O3 film by high temperature transformation of nanosized γ-AlOOH precursors

“…21 Furuta et al also studied boehmite films obtained after evaporation of the solvent of a boehmite solution synthesized via hydrothermal treatment of an aqueous solution of aluminium isopropoxide (or aluminium chloride) solution. 22 A strong increase in the ratio of the ( 020) and (120) peaks from I (020) /I (120) B 1.01 for the starting boehmite material (exhibiting a fiber-like morphology) to 51.4 for the boehmite film was again observed due to the parallel orientation of boehmite fibers to the surface.…”

“…Numerous studies performed on the microstructure of boehmite films often revealed an apparent preferential orientation of the boehmite particles. [20][21][22] For instance, Ouyang et al compared the XRD patterns of the powder and the film of a boehmite sample obtained from of an AlCl 3 -NH 3 precursor mixture at ambient temperature and observed the same strong enhancement of the (020) and (080) diffraction peaks attributed to a preferential orientation of the boehmite grains. 20 Similar results were obtained by Popa et al who studied boehmite films of different thickness by XRD.…”

Boehmite (γ‐AlOOH) nanoparticles: Hydrothermal synthesis, characterization, pH‐controlled morphologies, optical properties, and DFT calculations

“…Boehmite is an aluminum oxyhydroxide (γ‐AlOOH), which is used as a precursor for many aluminum oxide materials, especially for the preparation of ceramic catalysts 7, 8, membranes 9, coatings 10, 11, adsorbents 12–15, or materials with photoluminescent properties 16. Due to its biocompatibility, another important area of interest is the use of boehmite as an orthopedic or a dental material 17, 18.…”

Properties of boehmite and Al2O3 thin films prepared from boehmite nanofibres

“…Alumina is an important technical ceramic in industry and the films [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] have many applications. For example, the transparent thin films can be applied to not only opto-and photo-electronic fields [1][2][3][4] but also coatings for modifying the surface properties of the glasses, 5,6 plastics, 7 etc.…”
