SIZE OF BOEHMITE NANOPARTICLES BY TEM IMAGES ANALYSIS
Image Analysis & Stereology, 2011 Transition aluminas, and especially the gamma type, are largely used as catalyst supports in refining and petrochemicals. Most studies focus on properties resulting from material texture and casting (specific surface, porous volume, pore shape and diameter).

Rational descriptive classification of duricrusts [PDF]
, 1969 The term duricrust appears to be extending itself to include calcareous, gypseous, and saline crusts, in addition to crusts composed dominantly of silica and/or of sesquioxides of iron and aluminium, with or without significant contents of dioxides of ...

Kinetics of synthetic boehmite digestion
Journal of the Serbian Chemical Society, 1987 The boehmite synthesis was carried out by means of hydrothermal dehydroxylation of industrial gibbsite ; the physical and chemical properties of the samples having been determined previously. Analytical methods confirmed that boehmite contained excess water in comparison with the theoretical quantity to be contained by boehmite crystallized in the form
