Boehmite (next abbreviated as BA from boehmite alumina) is a versatile "preformed" nanofiller, which is also gaining acceptance in the preparation of polymer nanocomposites, as a result of its favorable properties. BA can be easily dispersed in various polymers and its distribution can be further enhanced by various surface treatments.
R. Rothon, P. Hornsby, in Polymer Green Flame Retardants, 2014 7.2 Boehmite. Boehmite has the composition AlO(OH) and has already been mentioned as an intermediate in the decomposition of aluminum hydroxide and is being promoted commercially as a flame retardant. As demonstrated in Table 6 and Figure 1, the onset of decomposition is significantly higher …

The spectral analysis of boehmite after adsorption was conducted to investigate the nature of adsorption sites of boehmite and the relationship between the surface groups and anionic contaminants. Compared with the pure boehmite, the IR spectra for Cr–AlOOH and NO 3 − –AlOOH are of prominently low intensity (figure 10 (A)), probably due ...
Thermodynamic calculations indicate that this transformation is driven by the shift in stability from boehmite to α-Al 2 O 3 caused by milling impacts on the surface energy. Structural water in boehmite plays a crucial role in generating and stabilizing α-Al 2 O 3 NPs. Corundum (α-Al 2 O 3) in high-surface-area nanoparticle (NP) form ( 1, 2 ...
The aluminum oxyhydroxide boehmite is an important crystalline phase in nature and industry. We report development of a flexible additive-free hydrothermal synthesis method to prepare high quality boehmite nanoplates with sizes ranging from under 20 nm to 5 μm via using hydrated alumina gels and aluminum hydroxide amorphous powders as precursors. The size …
1.The nanoparticle size of the material is small, and the diameter of the nanorod is less than 5nm. 2.The specific surface area (BET) of the product is large, about 250 m2/g. 3.Weak acidity (pH 4-5), which solves the release of acid gas in the use of aluminum sol. 4.The powder could be easily dispersed in the water to form a stable colloid ...
XRD result, which shows boehmite phase well devel-oped at 200°C. Furthermore, the XRD analysis indicates that the boehmite powder converts to γ-alumina by cal-cination at 500°C, the well-known process for the pre-paration of fine alumina from boehmite [24]. The infrared spectrum of individual samples is shown in figure 3.
