| Abstract: | Nanometer Al2O3 powder was prepared by chemical precipitation technique using NH4Al(SO4)2 · 12H2O and NH4HCO3 as the starting materials. The influences of pH value, surface active agents and ethanol on the size of Al2O3 powder were investigated. The mechanism of several antiagglomeration measurements and their effects on podwer size were discussed. |
