| Abstract: | Silica-glass was prepared by Sol-Gel process from tetraethylorthosilicate (TEOS). In the experiment, the influence on different preserving temperatures on the time of gel and the density of silica-glass was studied. The results show that when Sol-Gel is changed, preserving temperature and the time of gel have effect on the density of silica-glass in some extent. The higher the preserving temperature and the shorter the time of gel, the thinner the density of silica-glass. |
