The effects of Zn 2+ and Nb 5+ co-doping (x mol%ZN) on the electrical properties of lead-free Ba 0.90 Ca 0.10 Zr 0.10 Ti 0.90 O 3 -Seed ceramic systems, where x = 0.0-1.0 mol% have been studied. The ceramics were prepared using the solid state reaction technique. The phase of the samples showed pure perovskite structure. The density values of the ceramics were in the range of 4.86-5.78 g/cm 3 . The maximum dielectric constant was 40893 for 0.8 mol% ZN. The highest values of P r ∼ 5.85 μC/cm 2 , d 33 ∼ 381 pC/N and k p ∼ 38% were obtained for the sample of 0.4 mol% ZN. © 2014 Copyright Taylor and Francis Group, LLC.
