Abstract

Zirconia gels have been synthesized from zirconium butoxide in excess water with HNO3. The structure and characteristics of the gels have been studied as a function of the acid content, and the transformation during heat treatment has been followed up to 1150°C.

From the results of a previous similar study on aluminum hydroxide gels, a comparison is made between the sol-gel processes of zirconia and those of alumina. A discussion of the differences of the aqueous media chemistry of Al and Zr, and gelation mechanisms, is presented.
