Abstract

Features of both the ferroelectric and incommensurate transitions in Ba2NaNb5(1-x)Ta5xO15 were investigated by means of a transmission electron microscope in order to find the relationship between these transitions. An in situ observation of the transitions revealed that the ferroelectric transition takes place around 373 K in x=0.57 while the incommensurate transition occurs around 543 K. Because the ferroelectric transition does not basically accompany a change in microstructures related to the incommensurate lattice modulation, there is no interaction between these two transitions.
