The lead-free perovskite ceramics of (1-x) Ba0.96Li0.04TiO3-xBiYO(3) (BLT-xBY) (x = 0.02 similar to 0.10) were synthesized using traditional solid reaction sintering at 1250 degrees C. XRD and Raman spectra analysis showed that the phase structure transformation occurred at 0.06 = 0.08, the tetragonal phase disappears, and the orthorhombic phase and the cubic phase coexist. All the samples displayed almost pore-free microstructures with relative densities above 91. As x increases, the maximum permittivity decreases and moves towards low temperature. The dielectric constant at different frequencies shows dispersion phenomenon. When x = 0.08, the remnant polarization (P-r) and the maximum polarization (P-max) of the composition were 1.047 mu C cm(-2) and 11.643 mu C cm(-2), respectively. Meanwhile, the recoverable energy storage density (W-rec) is increased to 0.319 J cm(-3) with a high dielectric breakdown strength (BDS) of 69.2 kV cm(-1) at x = 0.08.
