Abstract
PbZn1/3Nb2/3O3-PbSc1/2Nb1/2O3-PbTiO3 solid solutions were studied alon g the (1 - u)(0.91PbZn(1/3)Nb(2/3)O(3) + 0.09PbTiO(3)) + u(0.58PbSc(1/ 2)Nb(1/2)O(3) + 0.42PbTiO(3)) and 45 mol % PbZn(1/3)Nb2/3O(3) sections . The PbZn1/3Nb2/3O3-rich samples contained a considerable amount of a nonferroelectric pyrochlore phase. At large u, only a perovskite phas e formed. Initially, the piezoelectric properties improved sharply wit h increasing u (decreasing content of the pyrochlore phase). Upon furt her increase in u, the properties leveled off, approaching values of p ractical significance. The morphotropic phase boundary was found to de flect toward low PbTiO3 contents.
