Synthesis and Characterization of Yttrium Doped Nano-zirconia by a Cationic Surfactant-assisted Route

1INTRODUCTION Zirconia is a kind of metal oxide material with high melting point(2700℃),high boiling point,small thermal conductivity,large coefficient of ther-mal expansion,high temperature resistance,good abrasive resistance and favorable resistance to corrosion.Due to its both acid and alkaline surface centers,zirconia is an ideal catalytic material with acid group bi-functions[1].In addition,owing to the excellent ionic exchange property as well as the chemical and mechanical stabilit…

Synthesis and Characterization of Yttrium Doped Nano-zirconia by a Cationic Surfactant-assisted Route

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 N2 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.
