Ip. Raevskii et al., Temperature-composition-degree of compositional ordering phase diagram of lead scandoniobate-scandotantalate solid solutions, TECH PHYS L, 24(12), 1998, pp. 945-946
It was established that the temperature of the ferroelectric phase transiti
on in crystals of compositionally ordered solid solutions of lead scandonio
bate-scandotantalate with high and low degrees of ordering S depends linear
ly on the composition x. These data were used to calculate the T-x-S phase
diagram of these solid solutions for the first time. (C) 1998 American Inst
