Piezoelectric ceramics(1-x)K0.458Na0.5420.96Li0.04 Nb0.85Ta0.15 O3-xBiFeO3 are prepared by traditional ceramic process. The phase structure is analyzed. Effects of Doping BF on Microstructure and Piezoelectric Propertiesof KNLNT Ceramics were investigated. The result reveal that the pure perovskite structures and piezoelectric properties of KNLNT ceramics by BFcontent addition. The piezoelectric constant of d33 increased firstly and decreased subsequently with the increase in content ofBF 。The properties were best when the content of BiFeO3 x=0.004:d33 =261 pC-N,Kp =0.6, Qm=42,Tc=337.86.
