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.
