Samples of 8 mol% Y 2 O 3 ‐stabilized ZrO 2 (8YSZ) doped with Fe were prepared and sintered at 1350°C in air or argon atmosphere. The sintered samples were characterized by SEM, XRD, and Raman spectroscopy. Raman spectroscopy and XRD were found to complement each other in phase identification; all the sintered samples were shown to possess tetragonal phase (t”) whose axial ratio (c/a) is equal to 1 in the cubic matrix. The Raman peak at 616 cm −1 , in general, was seen to broaden with increase in Fe concentration for both sintering atmospheres.
