Abstract: (26 Views)
High-performance piezoelectric materials are pivotal materials for many electromechanical applications, including piezoelectric actuators, sensors, and transducers. Achieving piezoelectric materials with high piezoelectric charge coefficient (d33) and Curie temperature (TC) has always been an important goal of researchers in the field of piezoelectric materials. Among piezoelectric materials, Relaxor-PT compounds have attracted much attention due to their excellent piezoelectric properties. In this paper, the structural and piezoelectric properties of PMN-PZT piezoceramic with the chemical formula 40[Pb(Mg1/3Nb2/3)O3]-25[PbZrO3]-35[PbTiO3] and PIN-PMN-PT piezoceramic with the chemical formula 25[Pb(Nb1/2In1/2)O3]-40[Pb(Mg1/3Nb2/3)O3-35PbTiO3 have been investigated. The results of the XRD pattern showed that the samples have a perovskite crystal structure. The results of the dielectric function measurement as a function of temperature showed that the Curie temperatures of the samples are 181 and 217 °C, respectively. This experiment also showed that the PIN-PMN-PT combination has higher thermal stability than PMN-PZT, which makes it suitable for high-temperature applications. The results of the electric polarization hysteresis loop and mechanical quality factor measurements showed that the PIN-PMN-PT composite is harder than the PMN-PZT piezoelectric. On the other hand, the PMN-PZT compound has a higher piezoelectric charge coefficient (d33=650 pC/N), piezoelectric voltage coefficient (g33=27 mVm/N), and planar electromechanical coupling coefficient (kp=49%) and therefore will have a higher sensing efficiency.
