| This research is concerned with the variations of mechanical, structural, physical, and magnetic properties of titanium dioxide (TiO 2) nanopowders produced via sol--gel method with annealing temperatures intervals 300 to 1100 C. The effects of the phase transitions on the main chracteristics of TiO 2 nanopowders are exstensively analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), and Vickers microhardness (H v) measurements. XRD investigations reveal an amorphous crystal structure at lower annealing temperatures (300--400 C), followed by the formation of the chracteristic anatase phase (450--500 C), and finally the transition to the rutile phase (600--1100 C). All TiO 2 nanopowders exhibit a tetragonal crystal structure. The avarage grain size parameter is found to increase depending on the lattice strain relaxation while dislocation density ... |
