The Development of High Performance Actuator Material with Low Lead Content Using the Spark-Plasma-Sintering Method

Abstract

In (Na0.5K0.5)NbO3, the competing ferroelectric and antiferroelectric interactions coexist. By modifying its disorder with PbTiO3, what will happen? Could the giant or colossal effect be possible? The objectives of the present research are to: 1)Characterize dielectric and piezoelectric properties of Na0.5K0.5)NbO3-PbTiO3 ceramics and 2)Investigate the effect of random fields on performance of perovskite piezoelectrics. This paper contains viewgraphs only.
