Colloidal silica which has high surface area and excellent surface properties are chemically stable inorganic materials and used for various applications in industry. Silica sol was prepared from sodium silicate solution by acid neutralization method and ion exchange treatment to remove sodium ions. Through the experimental analysis for controlling factors of particle growth rate, such as temperature, pH, and aging time, the uniform size distribution of silica sol could be obtained. The size distribution and shape of silica sol was measured by TEM and dynamic light scattering method. Zeta potential change and gelling phenomena of silica sol and its rheological properties also investigated.
