摘　　要：提供了一种制备高浓度、低黏度酸性硅溶胶的工艺方法 ,研究了二氧化硅粒径大小对酸性硅溶胶的稳定性及黏度的影响作用 ,得出要制备高浓度。This study provides a method for the preparation of high concentration and low viscosity acidic silica sol.We have found that the diameter of silicon particle is very important for the stability and viscosity of the acidic silica sol.The larger the diameter of the particle, the better the high concentration and low viscosity acidic silica sol prepare.

关 键 词：高浓度 酸性硅溶胶 制备 二氧化硅 粒径
