Modified barium titanates are widely used in transducers requiring moderate power level and receiving sensitivity. Special characteristics have made barium titanate a proven material for use in devices such as depth sounders and expendable hydrophones. Uses of this grade include: Low Power Sonar; Depth Sounders; Hydrophones; Shallow; Vibration Pickups; Receiver Transducers Coupling Constants: k33: 0.46 k31: -0.19 k15: 0.46 kp: -0.32 Piezoelectric Constants: d33: 145 x 10-12 m/V d31: -58 x 10-12 m/V d15: 245 x 10-12 m/V g33: 13.1 x 10-3 Vm/N g31: -5.2 x 10-3 Vm/N g15: 20.5 x 10-3 Vm/N.
