Effect of Glass Additive on Electrical Properties of PLZST Antiferroelectric Ceramics
Alkali-free barium boroaluminosilicate glass-modified PLZST antiferroelectric ceramics with glass contents between 0 and 8wt.% were fabricated respectively by a traditional solid phase reaction.The PLZST ceramics doped with alkali-free barium boroaluminosilicate glass showed typical nantiferroelectric phase when the glass contents were below 6wt.% and the refined grains were observed.The addition of glass decreased the dielectric constant of samples.With increasing of the glass additives,both the Curie temperature and the remanent polarization deceased.It may be that Ba2+ entered in the pcrovskite structure,which acts as an important modified ion in the alkali-free barium boroaluminosilicate glass.Larger forward antiferroelectric-ferroelectric phase transition field (EAFE-FE>50 kV/cm) and higher breakdown strength (EBDS≥105 kV/cm) were displayed in glass-modified PLZST ceramics.The improvement properties of samples were benefit for energy storage which is desired for the high power energy storage capacitors and pulsed power applications.
