Introduction to Sol-Gel Processing
2[yAlO(OH)] (7.2-1) Boehmite is composed of octahedral oxygen layers. The
bonding between two layers consists of hydrogen bonds, by the intermediate of
hydrogen atoms located between the terminal oxygen atoms of two boehmite
layers.

The density of boehmite is 3.01 g/cm3. Pseudo-boehmite is poorly crystalline and
is often the first crystalline form to appear when hydrous alumina gels are aged.
Certain of the XRD peaks in pseudo-boehmite are shifted relative to boehmite ...

Chemical Processing of Ceramics, Second Edition
With an increase in the carbon number of the alcohol, the yield of boehmite
decreases and the yield of ^-alumina increases.72 The latter compound is the
thermal dehydration product of gibbsite,75 and the highest yield of x-alumina is ...

Emerging Trends in Mineral Processing and Extractive Metallurgy
Generally boehmite is precipitated at 110-150°C in the presence of large quantity
of boehmite seed particles from sodium aluminate liquor. Precipitating boehmite
at 65-70°C is a challenging task. C. Misra et al. (2) produced pure boehmite at ...
