The Pb 0.99 Nb 0.02 ((Zr 0.52 Sn 0.48 ) 0.955 Ti 0.045 ) 0.98 O 3 antiferroelectric ceramics were synthesized by two different preparing routes (molten salt method and conventional solid state method). It was found that the sample synthesizes by a solid state method which owns smaller grain size leading to a higher energy storage density of 1.3 J/cm 3 . From the S-E loops, it was found that the sample prepared by a molten salt method owns less micro-cracks and larger grain size which induced a higher switchable polarization and strain. From the results of situ TEM, the existence of 90 ° domain indicates the existence of antiferroelectric phase.
