An easy synthesis route of YSZ (Yttria-Stabilized Zirconia) nanopowder with the formation of Zr0.92Y0.08O1.96 is synthetized by using thermal decomposition of ZrOCl2 and 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 ZrO2 and YSZ powders prepared via thermal decomposition had better crystallinity, and YSZ powders had perfect crystalline t-ZrO2 phase after heating at 650 °C, and changing the amount of PVA or the reaction precursors could obtain YSZ powders sized 20-50 nm.
