Abstract

In-situ micro Raman spectroscopy has been adopted as one of the most powerful analytical techniques with high spacial resolution under controlled atmospheres. In the present study, phase transformation of NiO doped yttria stabilized zirconia (YSZ) was monitored by in-situ micro-Raman spectroscopy. Raman spectra change caused by the phase transformation from the cubic phase to the tetragonal phase was observed for the NiO doped YSZ during annealing at a high temperature of 1173 K under reducing atmosphere.
