Effect of iron oxide loading on the phase transformation and physicochemical properties of nanosized mesoporous ZrO2

Effect of preparation conditions on structural and catalytic properties of lithium zirconate

“…It has been reported that monoclinic zirconium oxide exhibits Raman bands at 140, 173, 185, 216, 260, 301, 328, 342, 471, 500, 553 and 632 cm À 1 , with strong bands at 173, 185 and 472 cm À 1 and tetragonal zirconium oxide exhibits typical Raman bands at 148, 263, 325, 472, 608, and 640 cm À 1 , with a strong band at 263 cm À 1 [32]. Both LiZr-inorg-A and LiZr-inorg-B samples shows Raman bands due to monoclinic zirconium oxide and lithium zirconate phases.…”

Effect of fuels on conductivity, dielectric and humidity sensing properties of ZrO2 nanocrystals prepared by low temperature solution combustion method

“…The increase in surface area of ZrO 2 -2 is due to the small particle size. However the pore volume is lesser than ZrO 2 -1 shows the porosity difference in the samples [48].…”

Fe3O4 stabilized zirconia: structural, mechanical and optical properties

“…This reveals that Fe 3 O 4 results in stabilization of zirconia. Such stabilization might have occurred because of the difference in ionic radii of iron and zirconium ions [14]. The substitution/replacement of smaller iron ions (0.064 nm) with larger zirconium ions (0.079 nm) result in strain and stress in zirconia structure.…”

“…Basahel et al [14] reported the formation of pure tetragonal zirconia phase with relatively higher concentration of iron oxide (20 wt% of Fe 2 O 3 ) at 500°C. Whereas, in the present study, phase pure tetragonal zirconia was observed at 8-10 wt% of Fe 3 O 4 (basic) at temperature of 300°C.…”

“…5. This has been explained by considering a substitution of Fe ions, which have a smaller ionic radius than Zr [14]. Volume (Fig.…”
