Phase development and dielectric responses in PMN-BNT ceramics

Phase development and dielectric responses in PMN-BNT ceramics

(1 - x)Pb(Mg1/3Nb2/3)O3-x(Bi0.5Na0.5)TiO3 ceramics were prepared by the conventional mixed-oxide method. All compositions show complete perovskite solid solutions and the structure to change from cubic to rhombohedral at x = 0.5. The dielectric constant and dielectric loss tangent were measured as a...
