Lanthanum-free high-transparency ferroelectric ceramics PbMg1/3Nb2/3O3−xPbZr0.53Ti0.47O3(PMN-xPZT) have been prepared for the first time by a two-stage sintering method. The dielectric and electro-optical properties of the PMN-xPZT ceramics of different compositions, with the values ofxboth far from the morphotropic phase boundary (x= 10, 16, 23%) and close to it (x= 33%), have been studied. It has been shown that, in compositions lying closer to the morphotropic phase boundary (x= 23 and 33%), one observes, with no electric field applied, a first-order phase transition to a macrodomain ferroelectric phase, whereas the compositions far from the boundary (x= 10, 16%) persist in the relaxor cubic phase down to the low-temperature domain. It has been found that, in the ceramic withx= 33%, the quadratic electro-optical coefficients have at high temperatures (T> 340 K) the largest value among the relaxor systems, which expands the temperature interval of applicability of these solid solutions in industry.
