| Abstract: | Nano-porous material SiO2 aerogels were prepared from TEOS through sol-gel process and super critical drying technique. The effects of the amount of solvent used and the pH value of solution on the gelling process and the structure of the aerogels were studied. BET, XRD, SEM and some other experiment methods were used to investigate the structure and other physical properties of these aerogels. |
