| Özet |
| This research is concerned with the variations of mechanical, structural, physical, and magnetic properties of titanium dioxide (TiO2) 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 TiO2 nanopowders are exstensively analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), and Vickers microhardness (Hv) 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 TiO2 nanopowders exhibit a tetragonal crystal structure. The avarage grain size parameter is found to increase depending on the lattice strain relaxation while dislocation density … |
