Abstract
For many years the PLZT ceramics have been known as a ferroelectric material which has various electro-optic and piezoelectric properties. The aim of this work was to study how the lanthanum dopant (x) influences on the piezoelectric properties of x/65/35 PLZT ceramics. All samples were sintered by the hot uniaxial pressing method, from the sol-gel derived powders. The measurements enclose the complex of electric parameters, such as: , tg, k _p, k₃₁, d₃₁, S_E¹¹, g₃₁, V_R. The domain structures of unpoled and poled samples were conducted on the FESEM HITACHI S-4700.
