Raman scattering studies have been carried out on 12 mol% Ce-Tetragonal Zirconia Poly-crystal over 50-800cm-1, and a range of temperature 17-505K, a phase transition was observed from the tetragonal-like to monoclinic-like phase at approximately 165±1K when the temperature was lowering. The reverse transition occurred at approximately 450±2K when the temperature was raising.In order to study the reason of this transition, the condensation of the phonons in Brillouin zone and possible phase transition have been carefully discussed.
