Recently,　more　and　more　interest　has　been　focused　on　zirconia　for　its　unique　characteristics.　In　this　paper,　via　the　preceding　preparation　technique,　yttrium　can　be　successfully　incorporated　into　nano-zirconia　by　a　cationic　surfactant-assisted　route.　The　methods　of　XRD,　TEM,　EDS,　Uv-vis　and　N-2　adsorption-desorption　are　adopted　to　characterize　the　synthesized　samples.　The　results　show　that　the　yttrium　has　been　successfully　incorporated　into　the　zirconia　lattice,　and　the　thermal　stability　of　yttrium　doped　zirconia　has　been　enhanced　remarkably.
