Description

The results of experimental studies of Ba0.65Sr0.35TiO3 relaxor ceramics focused on glassy dynamics, tunability, and critical-like behavior in near paraelectric-ferroelectric phase transition region. The assessment of the sample properties included analysis of such parameters as the real part of dielectric permittivity and its reciprocal, the imaginary part of dielectric permittivity, loss tangent, relaxation times, and the maxima of loss curves. The sensitivity of the dielectric properties, in particular the dielectric constant, to the external electric field was also tested.


The dataset contains the results of:

  • the average particle size measurements (carried out using a Laser Scattering Particle Size Distribution Analyzer LA-950, HORIBA) of synthesized Ba0.65Sr0.35TiO3 powder;
  • microstructure analysis of the sintered Ba0.65Sr0.35TiO3 sample performed with scanning electron microscope Prisma E (Thermo Scientific);
  • broadband dielectric spectroscopy (BDS) measurements (carried out using Novocontrol Alpha-A analyzer) of the sintered Ba0.65Sr0.35TiO3 sample; data collected on cooling from 373 K to 123 K (251 temperature points) in the frequency range from 1 Hz to 10 MHz.
