ScholarBank@NUS Repository. https://doi.org/10.1016/S0022-2860(96)09397-0 | Abstract: | The Raman spectra of antiferroelectric NaNbO3 have been studied at temperatures up to 480°C. Two phase transitions were observed, one at 376°C in consistence with the previous observations, and the other being a new phase transition at 190°C. There is no evident hysteresis for this transition, which indicates that the phase transition is of second order. | Source Title: | Journal of Molecular Structure | URI: | http://scholarbank.nus.edu.sg/handle/10635/96797 | ISSN: | 00222860 | DOI: | 10.1016/S0022-2860(96)09397-0 |
