Abstract: Ternary Pb(In[sub 1/2]Nb[sub 1/2])O₃-Pb(Mg[sub 1/3]Nb[sub 2/3])O₃-PbTiO₃ (PIN-PMN-PT) single crystal was investigated for potential application in ultrasonic linear array. Orientation and temperature dependences of height extensional electromechanical coupling coefficient k′₃₃ for PIN-PMN-PT single crystal were studied. It was found that the [001] poled PIN-PMN-PT diced along the [100] direction would achieve a maximum k′₃₃ (∼87%) and the service temperature was up to 110 °C. Ultrasonic linear arrays using PIN-PMN-PT single crystal and PZT ceramic were fabricated and compared. The bandwidth at −6 dB, two-way insertion loss and pulse length of the PIN-PMN-PT array were 98.6%, −45.1 dB, and 0.28 μs, respectively, which were about 25% broader, 3.7dB higher, and 0.08 μs shorter than those of the PZT array. The experimental results agreed well with the theoretical simulation. These superior performances were attributable to the excellent piezoelectric properties of PIN-PMN-PT single crystal
