| Abstract: | Gelcasting process was adopted to prepare fused silica ceramic in which nanometer silica was introduced as a dopant. Material properties were tested and analyzed. Experimental results have indicated that nanometer silica particle can be well dispersed in ceramic matrix. With the help of the nanometer phase, the sintering process was speeded up and improved. As a result, both density and strength of the material were increased. |
