Abstract

Abstract: Ultrafine high-purity alumina has been prepared by hydrolysis of aluminium isopropylate in yield 95%. By this technology the isopropyl alcohol from alcoholed can be recovered and used repeatedly. The α-Al₂O₃ obtained by this process has a high-bulk density with relative uniform particle size.The average particle size is 0.3 to 0.03 μm, in purify of 99.99%.

Key words: aluminium isopropylate, hydrolysis, alumina, ultra-fine powder, preparation
