Abstract:

The preparation of yttria-stabilised zirconia (YSZ) sol and the mechanismsof sol formation and sol-gel transition have been studied. The YSZ sol was prepared viacontrolled hydration of propanol zirconia alkoxide doped with yttrium nitrite. The sol formation process and gelling time are affected by many parameters such as water content,acetic acid content and the amount of propanol. The stability of the sol can be greatlyimproved by adding appropriate polymer.

Key words: Alkoxide, Sol-gel method
