چکیده انگلیسی
The coarse agglomerates of gibbsite (γ-Al(OH)3) are grateful starting materials for preparation aluminum oxides and hydroxides as boehmite and γ-Al2O3, which are extensively used as a catalysts and catalyst support for the petrochemical industry. By preparing the boehmite particles from the gibbsite and product of the heat gibbsite, we demonstrate the influence of different treatments to a morphology and particle size of the formed boehmite (γ-AlOOH). It is been established for the first time that the flaky-shaped 2D γ-AlOOH particles are formed within the coarse agglomerates producing a laminated packaging film lozenge-shaped crystals which results in a 0.1 cm3/g pore volume and 29 m2/g specific surface area. The obtained data have a high industrial importance in the area of producing materials based on the coarse boehmite agglomerates with different properties.
