文摘The NaNbO3 powders were synthesized and their crystal structure changes were analyzed by ultrahigh pressure up to 6 GPa.The results indicate that the pure NaNbO3 powders can be synthesized at 300℃ under a pressure of 4 GPa, to sig- nificantly restrain the Na element volatilization compared with the traditional syn- thesis method. It is found that the crystal structure of synthesized NaNbO3 changes from low symmetry to high symmetry with the increase of the pressure.
