| Abstract：By using tetraethylortho silicate, ammonia, n-propanol and water as materials, the mono-disperse silica micro-sphere in semi-micron and micron level was synthesized. The effects of factors on the reaction have been studied. The experiment condition for production of mono-disperse silica micro-sphere with different diameter was given at last. |
| Key words：Tetraethylortho silicate; Silica micro-sphere; N-propanol |
