Abstract

Nano-porous ZrO₂ aerogels were prepared with zirconyl nitrate dihydrate (ZrO (NO₃)₂·5H₂O) by heating hydro-thermal method subseqently supercritical drying technique. The prepared aerogels are performed by SEM and BET to characterize and analyze the morphology and pores characteric of ZrO₂ aerogels. The results showed that: The areogels are the typical of nano pores in the interval between 5<Dp<60 nm; the specific surface areas reach 916.5 m²/g; There is a homogeneous pore distribution in aerogel. Morever the gel process was also discussed in this research.
