Effect of Zn~(2+) and Nb~(5+) Co-Doping on Electrical Properties of BCZT Ceramics by the Seed-Induced Method

摘要

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 glcm3. 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.
