Preparation of Nano-Scale a-Al2O3 Powder by the Sol-Gel Method.

Sol-gel method was applied to synthesize ultrafine nano α-alumina particles using aqueous solutions of aluminum isopropoxide and 0.5 M aluminum nitrate hydrate. Sodium dodecylbenzen suffocate and Sodium bis-2ethylhexyl sulfosuccinate were also used as surfactant stabilizing agents. The prepared so...
