| Abstract: | Dispersed nano Al 2O 3 particles were prepared by the hydrolysis of metal alkoxides in isopropanol solution with the method of two step. The effect of reactive condition on particle size and distribution was investigated systematically. The size of prepared particles varies from 20 nm to 100 nm along with the change of reactive condition. |
