| Abstract: | Ultrafine silica powders are prepared by sol-gel method which used tetraethyl orthosilicate as precursor. The optimization process of preparing ultrafine silica powders has been found out by controlling the ratio of raw materials, temperature, catalyst and other factors, and by analyzing the effect of gelling status, the gelling time and the particles size of products. The heat-treated final powders were characterized by particle-size analyzer. |
