In this paper, in order to develop the low temperature sintering ceramics for the application of ultrasonic transducer for nondestructive testing, Pb(Ni 1/3 Nb 2/3 )O 3 ?Pb(Zr,Ti)O 3 [PNN?PZT] substituted with Pb(Mg 1/2 W 1/2 )O 3 ceramics were manufactured using PbO, CuO and Sb 2 O 5 as sintering aids, and their microstructural, dielectric and piezoelectric properties were investigated. At 0.5 wt% antimony oxide (= Sb 2 O 5 ) added specimen sintered at 910 [℃], the maximum values of piezoelectric properties were shown, respectively: the dielectric constant (εr ) of 1,120, piezoelectric constant (d 33 ) of 379 [pC/N], electromechanical coupling factor (k p ) of 0.648, piezoelectric charge constant g 33 of 38.2 [mV m/N] and mechanical quality factor (Q m ) of 116 were suitable for the device application such as ultrasonic transducer and piezoelectric actuator.
