文摘
- •
Phase separation in NaTaO3 studied using high resolution powder diffraction.
- •
At room temperature Pbnm and Cmcm phase co-exist in polycrystalline NaTaO3 samples.
- •
Annealing has little impact on the phase distribution at room temperature.
- •
Doping has a significant impact on phase separation, tending to favour the Cmcm phase.
