Abstract:
Barium aluminate BaAl2O4 of spinel structure was prepared by hydrothermal treatment at 150°С of a
suspension of a gibbsite thermal activation product in an aqueous barium nitrate solution, followed by heat treatment
of the precursors obtained. The product composition was studied by X-ray diffraction, thermal, microscopic,
adsorption, and chemical analysis methods. Heat treatment of the hydrothermal reaction products at 850°С leads
to the formation of single-phase barium aluminate BaAl2O4 with the specific surface area of ~50 m2 g–1 in the
form of disk-shaped porous particles forming aggregates. The surface of BaAl2O4 particles is enriched in barium
cations, which are relatively uniformly distributed over particles. The procedure allows reduction of the amount
of the starting reactants and of the number of preparation steps, and also minimization or complete exclusion of
the wash water formation.
