Dielectric diffusive behavior of (Lax(Na0.5Bi0.5)1-1.5x)0.97Ba0.03TiO3 lead-free ceramics

We investigate in the present work the additional data to the previous reported paper (Zhao, et al.) that sufficiently enrich to understand the dielectric diffusive behavior of the (La-x(Na0.5Bi0.5)(1-1.5x))(0.97)Ba0.03TiO3 lead-free ceramics. The dielectric diffusive behavior of the ceramics was investigated using Lorentz-type quadratic relationship and Gaussian-type quadratic relationship. By calculating mean-square-root error and dielectric constant variance, it was found that Lorenz-type quadratic relationship was better to describe the characterization of dielectric diffusive behavior than Gaussian-type quadratic relationship. The results confirm that the increase in La3+ content causes an increase in the degree of diffuseness of dielectric peak. (C) 2016 Elsevier B.V. All rights reserved.
