The second endothermic peak, at 504 [degrees]C in the DSC curve, accounted for approximately 10% of the weight loss in the TG curve and was attributed to boehmite
In general, the surface of APA is considered to be amorphous [Al.sub.2][O.sub.3] , which changes to a boehmite
layer as a result of the treatment of the APA in water above 90[degrees]C .
Diaspore is primarily aluminum oxide-hydroxide and may contain other aluminum containing minerals such as bauxite, gibbsite, boehmite
along with other minerals of the elements like chromium, iron, silicon, calcium, magnesium as the minor constituents .

Occasionally, we found boehmite
[[gamma]-AlO(OH)], characterized by three Raman peaks at 362, 495 and 675 [cm.sup.-1], the first being the most intense (Figure 10f).

surfaces: A solution chemistry and XANES spectroscopy study.
X-ray diffraction (XRD) analyses show that the Zan laterites consist of kaolinite, diaspore, hematite, goethite, boehmite
, anatase, siderite, rutile, and quartz.

 results in which they found that SDBS can partially ionize in water and give anionic species, while the boehmite
holds positive charges in a neural aqueous medium, showing a strong affinity for anionic groups.
(31) used roughness parameters to relate the superhydrophobic and AR properties of boehmite
In lithofacies-1 (laterite / bauxite / kaolinite) the goethite, kaolinite, boehmite
, gibbsite and dickite minerals may owe to insitu leaching of older rocks.
All ABx bauxites are free of the refractory, high-temperature monohydrate alumina mineral called boehmite
and, equally importantly, the levels of the deleterious reactive silica are very low.
