Structure, electrical, and thermal expansion properties of PZnTe–PZT ternary system piezoelectric ceramics

x P b(Zn 0.5 Te 0.5 )O 3 –(1− x )Pb(Zr 0.5 Ti 0.5 )O 3 ( PZ nTe– PZT ) ceramics were prepared by the solid‐state reaction method. The phase structure, microstructure, ferroelectric and dielectric properties and thermal expansion properties were systematically investigated. X‐ray diffraction analysis showed the morphotropic phase boundary ( MPB ) existed at the composition of x = 0.08, which was the coexistence of the rhombohedral phase and the...
