Zirconia (ZrO₂) nanopowder was synthesized using sucrose and fructose as a chelating agent from zirconium hydroxide. The
synthesized powders were characterized by X-ray diffraction (XRD), simultaneously thermal analysis (STA), BET surface
area, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The above-experimental results
showed that the synthesized powders had particle sizes in the range 40-60 nm and mean crystallite sizes of 7-8 nm. Finally,
in this research, chelating agents of sucrose and fructose were compared and the obtained results demonstrated that using
fructose, nanopowder of zirconia with tetragonal phase was obtained. |
