Abstract

Compare lead zirconate titanate (PZT), a new generation relaxor-PT material that shows significantly improved properties with very high electromechanical coupling and piezoelectric coefficients, which makes them optimistic piezoelectric materials for various applications like sensors, transducers, and actuators. In this paper, we discuss the status of binary relaxor-PT materials such as lead zinc niobate - lead titanate (PZN–PT), lead magnesium niobate - lead titanate (PMN–PT), lead scandium niobate - lead titanate (PSN-PT), lead indium niobate - lead titanate (PIN-PT), and lead nickel niobate - lead titanate (PNN-PT) and ternary relaxor-PT materials lead indium niobate -lead magnesium niobate - lead titanate (PIN-PMN-PT), lead indium niobate - lead zinc niobate - lead titanate (PIN-PZN-PT), lead zinc niobate - lead magnesium niobate - lead titanate (PZN-PMN-PT), and lead scandium niobate - lead magnesium niobate - lead titanate (PSN-PMN-PT).
