Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <p id="spar0005">Tetragonal and cubic zirconia nanoparticles were hydrothermally prepared and calcinated at different temperature. X-ray diffraction <italic>via</italic> Rietveld refinement is used to study the crystalline structure of nanoparticles. Results show that as-prepared tetragonal nanoparticles exhibit a crystalline structure with distorted lattice; the crystalline structure evolutes with the increasing calcination temperature and the distorted lattice is recovered after nanoparticles were calcinated at temperature higher than 900 °C. The cause for lattice distortion of tetragonal nanoparticles is discussed and is explained in term of the incorporations of hydroxyls into its lattice during preparation.</p> </sec> </abstract>
