The Dynamic Laser Scattering(DLS) Investigation on the Hydrolytic Polycondensation of Tetraethylorthosilicate(TEOS);

Influences of the Catalyzing Mode and the Ratio of Water on TEOS Sol-Gel Processing;

The Effect of Catalysts on TEOS Hydrolysis-Condensation Mechanism;

Synthesis of silica film using tetraethylorthosilicate;

Tetraethylorthosilicate(TEOS) was used as source material and hydrochloric acid or ammonia was used as catalyst to prepare SiO_2.

The studies indicate that the order of the grade influencing the average diameter is the water content is in the first place,ethanol the second,ammonia the third,and tetraethylorthosilicate the l.

Nanosize SiO_(2) particles were prepared using water-in-oil microemulsion method in polyether polyol with hydrolysis and condensation reactions of tetraethyl orthosilicate(TEOS) by means of controlling molar ratio of water to surfactant and selecting moderate hydrolysis temperature.

Porous carbons were prepared by using a sol-gel method with tetraethyl orthosilicate (TEOS) as the silica template and sucrose as carbon precursor and adding N,N- dimethyl formamide(DMF) as drying control chemical additive(DCCA).

The silica MSU-X type mesoporous molecular sieves were synthesized by using the polyoxyethylene stearyl ether (C18EO10) as template, the tetraethyl orthosilicate (TEOS) and sodium silicates as silica source, respectively.
