0.8) composite ceramics were prepared by the traditional solid-state reaction method. The structural

dielectric

ferroelectric and piezoelectric properties of the ceramics were investigated. XRD results show that all the ceramics show typical tetragonal perovskite structures

with various lattice parameters induced by different amounts of BiFeO

concentration. The dielectric permittivitytemperature curve shows that

both the temperature of phase transition and the value of dielectr

ic permittivity have been affected by theBiFeO

concentration. It has been found that

at the room temperature

dielectric permittivity of the ceramics increases with the increase of the BiFeO

concentration. And the diffuse phase transition has been observed in the ceramics. Besides

all samples show clear ferroelectric and piezoelectric characteristics

and these characteristics change in the same trends along with the BiFeO

concentration.
