Substitution of Pb with (Li1∕2Bi1∕2) in PbZrO3-based antiferroelectric ceramics

PbZrO3-based antiferroelectric (AFE) ceramics are promising dielectrics for high-energy-density capacitors due to their reversible phase transitions during charge–discharge cycles. In this work, a new composition series, [Pb 0 . 9 3 − x La 0 . 0 2 (Li 1 ∕ 2 Bi 1 ∕ 2 ) x Sr 0 . 0 4 ][Zr 0 . 5 7 Sn 0...

Description
Summary:PbZrO3-based antiferroelectric (AFE) ceramics are promising dielectrics for high-energy-density capacitors due to their reversible phase transitions during charge–discharge cycles. In this work, a new composition series, [Pb 0 . 9 3 − x La 0 . 0 2 (Li 1 ∕ 2 Bi 1 ∕ 2 ) x Sr 0 . 0 4 ][Zr 0 . 5 7 Sn 0 . 3 4 Ti 0 . 0 9 ]O3, with Li + and Bi 3 + substitution of Pb 2 + at x = 0 , 0.04, 0.08, 0.12, 0.16 is investigated for the microstructure evolution, ferroelectric (FE) and dielectric properties. It is found that Li + and Bi 3 + substitution can significantly reduce the sintering temperature and simultaneously enhance the dielectric breakdown strength. An ultrahigh energy efficiency (94.0%) and a large energy density (3.22 J/cm 3 ) are achieved in the composition of x = 0 . 1 2 with a low sintering temperature (1075∘C).
