The xBi(Zn2/3Nb1/3)O3–(1−x)(K0.5Na0.5)NbO3 (abbreviated as xBZN–(1−x)KNN) ceramics have been synthesized using the conventional solid-state sintering method. The phase structure, dielectric properties and “relaxorlike” behavior of the ceramics were investigated. The 0.03BZN–0.97KNN ceramics show a b...
