摘要
硅溶胶是二氧化硅微粒在水中均匀扩散形成的胶体溶液,有酸性和碱性之分。本文简要介绍了硅溶胶的结构及稳定机理,综述了影响硅溶胶稳定性的系列因素,包括pH值、粒径、电解质等,并对硅溶胶的研究前景进行了展望。
Silica sol is a kind of colloid solution well dispersing corpuscles of silica in water,and has been classified into two groups,i.e.basic and acidic silica sols.In this paper,the structure and the stable mechanism of silica were introduced.It is also summarized the stability influencing factor of silica,including pH,particle size,electrolyte and so on.Meanwhile,the research prospect of silica sol was also forecasted.
