The polyhedral oligomeric silsesquioxane(POSS)-zirconia aerogels which contain three different contents of zirconia were successfully prepared from the POSS-［C2H4Si(OEt)3］8 and Zr(OC4H9)4 by the sol-gel process and subsequently supercritical drying with carbon dioxide. Ethanol was used as the solvent during the process. The samples were characterized by FTIR, SEM, XRD and BET. The results indicate that the three samples all have homogeneous Si-O-Ti bonds, and they are amorphous. The BET surface areas decrease with the increasing of the contents of zirconia, the biggest surface area is 491 m2/g, and all the pore distributions of the three samples are broad.
