Abstract
An easy synthesis route of YSZ (Yttria-Stabilized Zirconia) nanopowder with the formation of Zr0.92Y0.08O1.96is synthetized by using thermal decomposition of ZrOCl2and Y(NO3)3, with polyvinyl alcohol (PVA) as surface active agent and with quantitative filter paper as carrier. The roasting temperature of YSZ precursor was 650oC. The results of SEM and XRD analysis showed that the pure ZrO2and YSZ powders prepared via thermal decomposition had better crystallinity, and YSZ powders had perfect crystalline t-ZrO2phase after heating at 650 °C, and changing the amount of PVA or the reaction precursors could obtain YSZ powders sized 20-50 nm.
