Large hydrostatic piezoelectric coefficient, dh - 111 pC/N, for compositions in the system (1-x) Bi(NiTi)1/2O3: (x) PbTiO3[BPNT] has been reported in this paper. Temperature dependencies of the dielectric, elastic, and piezoelectric properties of two compositions, x = 0.40 and x = 0.50, around the morphotropic phase boundary of Mn+2 doped BPNT ceramics have been studied. Room temperature dielectric hysteresis loops with Pr = 37.86 μC/cm2 and Ec = 25.75 kV/cm were observed for x = 0.40. Electromechanical coupling factors, kp = 32.5%, k31 = 19.7%, and kt = 57.1% and piezoelectric constants, d33 = 250 pC/N, d31 = -67 pC/N, and dh = 111 pC/N were measured in the BPNT-40 composition. The hydrophone figure of merit, dhgh ≈ 1055 × 10-15 m2/N was calculated from these measurements. |
