Fig. 4: Lattice distortion, and electric resistance of entropy-assisted BNT-based ceramics and MLCCs.

a The unit cell c/a ratios of the BNSLTMZ ceramics along the [100]c zone axis, the color of the circles indicates the c/a ratio for each unit cell. b SEM images and grain size distributions of the BNT, BNSLT, and BNSLTMZ ceramics, \(\bar{d}\) represents the average grain size. c Impedance spectra of the BNT, BNSLT, and BNSLTMZ ceramics at 600 °C. d Weibull distribution analysis of the breakdown strength of the BNT, BNSLT, and BNSLTMZ ceramics and MLCCs.
