Abstract

Fibrillar boehmite (γ-A100H) is used to synthesize an acicular form of the defect spinel γ-Al₂O₃, an important support material for catalysts. Acicular γ-A100H was prepared by the addition of powdered aluminum to an aluminum chloride solution with an $A 1 C 1$ ratio of $23$ . The basic aluminum chloride solution was diluted and treated hydrothermally at 160°C for 40 hours. TEM, x-ray analysis and I. R. Spectra were used to characterize the product.

Acicular γ-Al₂O₃ was obtained by thermal decomposition of the fibrillar boehmite at 400°C for 72 hours.

The role of tetraethyl ammonium hydroxide on the phase determination and electrical properties of γ-MnOOH synthesized by hydrothermal
2001, Materials Letters
γ-MnOOH was synthesized by hydrothermal method at low temperature in the presence of tetraethyl ammonium hydroxide [TAH]. The phase of the final product was observed to be sensitive for the concentration of [TAH]. γ-MnOOH appeared as a pure and single phase, for the concentration range from 0.1 to 0.5 mole with respect to Mn. The powder prepared was found to have fiber morphology with a high surface area of 71.8 m²/g. Thermal and chemical analysis of γ-MnOOH have been made by TGA/DTA, FTIR and DCP. This study indicates that the concentration of [TAH] affects the conductivity of the powder. The conductivity was explained in terms of the phase obtained in the final product after hydrothermal treatment.
Hydrothermal crystallization of boehmite from freshly precipitated aluminum hydroxide
1999, Materials Letters
Hydrothermal crystallization of boehmite from freshly precipitated aluminium hydroxide was monitored using X-ray powder diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. Crystallite sizes and interplanar spacings for boehmite samples were determined. Changes in the crystallinity of boehmite influenced the corresponding FT-IR spectra. The maximum specific area for boehmite powder was 246 m² g⁻¹, as measured by the Brunauer–Emmet–Teller (BET) method. With an increase of the crystallinity of boehmite, the specific area decreased and for the best crystalline sample, was 91 m² g⁻¹. All boehmite samples contained particles of colloidal dimensions. For the best crystalline boehmite sample, hexagonal-like plates were observed and some of them were elongated.
Microstructural properties of boehmite formed under hydrothermal conditions
1998, Materials Science and Engineering B
The microstructural properties of boehmite formed in an alkaline medium under hydrothermal conditions were investigated using X-ray diffraction (XRD), Fourier transform IR (FT-IR) spectroscopy, transmission electron microscopy (TEM) and microelectrophoresis. The bayerite formed at the beginning of the precipitation process converted to boehmite by the dissolution/reprecipitation mechanism. Boehmite crystallites were in the nanosize range and of anisotropic shape, as determined by XRD. A tendency toward an increase in the crystallite size with prolonged duration of autoclaving was evident both at 160 and 120°C. The boehmite particles produced by autoclaving at 160°C for 10 h looked like thin microfoils, i.e. different from the boehmite morphology usually obtained (rods, fibrils and very small plates). The factors that influence the pH_iep of boehmite particles are discussed. The FT-IR spectra of bayerite and boehmite are interpreted.
Formation of boehmite via precipitation from aqueous solutions
1995, Materials Letters
Colloidal particles of boehmite, formed by precipitation from AlCl₃ solutions, have been investigated using X-ray diffraction, Fourier transform infrared spectroscopy and transmission electron microscopy. Strong effects of the pH of precipitation of aluminium hydroxide and the mode of its drying on the phase composition of the precipitate were observed. The experimental conditions for the preparation of boehmite films, without use of Al-organic precursor or organic peptizing agents, were determined. It was found that the crystallite size in the boehmite films was of the order of 2 to 3 nm.
Preparation and characterization of transparent γ-AlOOH films
1994, Materials Letters
Experimental conditions for the preparation of transparent γ-AlOOH (boehmite) films were investigated. Transmission electron microscopy revealed a fibrous morphology of γ-AlOOH particles. Transparency of the films for visible light was preserved up to 900°C, while after heating up to 1050°C the film became white. X-ray powder diffraction showed the transitions from γAlOOH (90°C) to γ-Al₂O₃ (500 to 900°C) and finally to α-Al₂O₃ andθ-Al₂O₃ (1050°C). Electrical conductivity of the films was measured.
