- Abstract
In the present work, nano-sized γ-alumina powders have been successfully synthesized by control precipitation path using aluminum chloride as forerunner and water and ammonium solution as precipitating agents and at 70 °C. The synthesized γ-alumina samples have been characterized by XRD, AFM, SEM, and N2-adsorption/desorption isotherm at -196 °C by the BET method. Different initial concentrations of aluminium chloride precursor in ethanol solvent were studied on the particle size and surface area of the prepared γ-alumina. Results indicates that the sample prepared by this method gave nano-sized particle with crystallite shape in the range 70-91 nm, surface area 260-291 m²/g and pore volume 0.467-0.36 cm³/g.
