The EXAFS study of nanocrystalline zirconia

Abstract
We performed temperature-dependent extended X-ray absorption fine structure (EXAFS) measurements on a series of nanocrystalline zirconia powders with different crystallite sizes. The results show that there is a tetragonal-to-cubic phase transition with reduction of crystallite size. The temperature dependence of the EXAFS Debye-Waller factor is also discussed.
