摘　　要：利用硝酸铝、壬基酚聚氧乙烯醚、环己烷、丁醇和水制成W /O微乳液。利用这种微乳液制成水合氧化铝超细粒子。经 3 5 0℃烘干成γ -氧化铝 ,再经 12 0 0℃灼烧后变成其粒径 <5 0nm的α -氧化铝超细粒子 ,并由比表面测定X -衍射光谱对其进行了表征。此方法具有设备简单、操作容易。A W/O microemulsion of Al(NO 3) 3,OP-7,cyclohexane,n-butanol and water was prepared.Aluminium hydrous oxide ultrafine particles were prepared in the microemulsion,α-Al 2O 3 particles with mean diameter smaller than 50 nm were obtained after calcination at 1 200 ℃.These ultrafine particles were characterized by DTC,BET,XRD.Furthermore,the required equipment is simple,operation is easy,and particle size can be controlled by yourself.All of these are the advantages of this technique.
