The dataset of the BCZT ceramic characterizations

All original data used in figures and tables of the manuscript are
available in the dataset, which includes the XRD, variable temperature
dielectric, room temperature frequency spectrum and ferroelectric
performance measurements.A sol-gel method is employed for preparing high
quality lead-free glass-ceramic samples (1-x) BCZT-x BBS – incorporating
Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) powder and Bi2O3-B2O3-SiO2 (BBS) glass
doped additives with different values of x (x = 0, 0.05, 0.1, 0.15). With
the increase of BBS content, the polarization degree gradually decreases,
but the breakdown electric field intensity first increases and then
decreases, reaching the maximum value of 141 kV/cm when x =0.1. The energy
storage density is calculated according to the electric field and
polarization intensity. The maximum energy storage density reaches 0.3907
Jcm-3 at electric field of 130 kV/cm as x value is 0.05.
