Synthesis and structural transformation of zirconia aerogels

Zirconia (ZrO[sub 2]) aerogels were prepared by the sol-gel method using zirconium n-propoxide in n-propanol followed by supercritical drying with carbon dioxide. This synthesis, without the use of dopants, formed a high surface area material and stabilized the tetragonal phase at low temperatures....
