| 摘 要： | 以正硅酸乙酯为硅源，氨水调节体系pH值，采用沉淀法制备二氧化硅微球。考察了聚乙二醇、曲拉通X-100、吐温-80等非离子表面活性剂对二氧化硅微球形貌的影响，通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）以及X射线衍射对其进行表征。结果表明，表面活性剂的种类不同，加入量不同，可制备出粒径范围在80～600nm左右的光滑的二氧化硅微球。

| Abstract: | SiO2 microspheres were synthesized by a precipitation method, using raw materials of tetraethyl orthosilicate as silicon source, ammonia as a precipitant, and cyclohexane as a solvent. The effects of various surfactants, polyglycol, Triton X-100, and Tween-80, were investigated. The products were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, and transmission electron microscopy （TEM）. The results indicated that the prepared SiO2 was approximately spherical with an average particle size of 80-600 nm. |
