Emulsion-based synthesis of unaggregated, spherical alpha alumina

摘要

Unaggregated spherical α-alumina powder was prepared by the controlled hydrolysis of Al(Opr~I)_3 in a dilute solution consisting of CH_3 (CH_2)_6CH_2OH and CH_3CN. Spherical AlOOH precursors crystallized to γ-alumina at 1000 ℃ and converted to α-alumina a
