The dielectric constant of the BNLT ceramic was enhanced by BZT incorporation. The dielectric constant was maximized with the 0.09BZT incorporation. The temperature of the dielectric peak of BNLT ceramic decreased while the degree of diffuse phase transition increased with BZT substitution. The polarization–electric field (P–E) curve measured at temperature above 30 °C was found to be slimmer with increasing BZT content. The remnant polarization of the BZT-incorporated ceramics decreased with increasing temperature. The observed results were believed to be caused by the lattice distortion and the enhanced cation disorders in A and B-site lattices due to the incorporation of Ba2+ and Zr4+ ions into A and B-site lattices, respectively, of BNLT perovskite structure. 2018-09-04T10:14:24Z 2018-09-04T10:14:24Z 2015-11-01 Journal 1573482X 09574522 2-s2.0-84943359491 10.1007/s10854-015-3515-0 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84943359491&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/54475
