用透射电镜对乙醇介质中氨催化下正硅酸乙酯（ＴＥＯＳ）水解制各单分散二氧化硅微粒过程中颗粒的生长过程进行了跟踪，通过对ＴＥＯＳ的水解速率与成核及颗粒生长速率间关系的研究，发现水解是整个反应的控制步骤，影响水解的因素也同样影响成核及颗粒的生长。
Transmission electron microscopy (TEM) was used to trace the growth of particles during the hydrolysis of tetraethyl orthosilicate (TEOS) catalyzed by ammonia catalyzed by ammonia in ethanol. The hydrolysis rate, nucleation and particle growth rate The relationship between the study found that hydrolysis is the control of the reaction step, the factors that affect the hydrolysis also affect the nucleation and particle growth.
