Abstract
Ceramic samples of the mixed system Ba2NaNb5(1-x)Ta5xO15 were investig ated through dielectric and Raman scattering measurements. It was reve aled that with the increase of x from 0 to 1, the ferroelectric Curie point decreases from 833 K to about 40 K, whereas the ferroelastic pha se transition point decreases from 573 k to the 250 K range.
