Abstract

The mixed ZrO2–TiO2 system (5–50 wt% of ZrO2) has been studied to investigate the influenceof the mechanical treatment on its physicochemical properties depending on the composition, timeof milling (5, 10 and 20 min, r.p.m. 82) and temperature (400, 550 and 700 C). Samples werecharacterized by Raman spectroscopy, X-ray powder diffraction, Scanning Electron Microscopy coupledwith Energy Dispersion X-ray analyzer, High Resolution-Transmission Electron Microscopy andnitrogen adsorption porosimetry. Results show that srilankite (TiZrO4) phase has been produced. Noinfluence of the milling time and temperature on the phase composition is observed. The presenceof zirconia increases the thermal stability of anatase phase up to 700 C hindering the anatase—rutile phase transformation.
