“…Moreover, piezoelectrics function with no electromagnetic noise. 7 From the viewpoint of the piezoelectric material, actuators may be classified as working in the small or large signal regime, as depicted in Figure 1.1. The small signal regime indicates that the piezoelectric responds linearly to an electric field input, on the order of 0.0005 kV/mm.…”

Effect of MgO on ferroelectric, dielectric, piezoelectric properties of (Ba 1-x Mg x ) (Ti 0.98 Zr 0.02 ) O 3 , (x = 0.00, 0.01, 0.015, 0.02 and 0.03 mol) lead free piezoceramics was studied. The powders were prepared by conventional solid state reaction method, calcined at 1000°C for 4 h. XRD patterns of the calcined powders show phase pure perovskite structure. The calcined powders were deagglomerated, pressed into pellets and sintered at 1150°C for 3 h. Scanning electron microscopy studies of thermally etched sintered pellets show sub-micron sized grains for undoped BZT and 3-5 lm sized grains for 0.01 mol MgO doped BZT. Energy dispersive X-ray analysis of MgO doped BZT sample confirms the presence of dopants very close to their stoichiometric compositions. The piezoelectric charge constant (d 33 = 164 pC/N), dielectric constant (K = 2348) and remnant polarization (P r = 3.3 lC/cm 2 ) were maximum for BZT samples containing 0.01 mol of MgO.

“…The La-doped lead zirconate titanate (PLZT) piezoelectric ceramics have been used for the transducer as well as in the actuator devices (Haertling 1999;Uchino 2008). Apart from the technological applications, the PLZT ceramics show normal ferroelectric phase transition to relaxor characteristics in a series of compositions by varying the La concentration in the base lead zirconate titanate (PZT) systems (Dai et al 1994).…”
