Abstract

The industrial and scientific communities have expressed the need for sensing and actuation over a broad temperature range. This review presents high temperature piezoelectric materials that are commercially available and those that are under development. Key materials, in order of increasing Curie Temperature (Tc), are Pb(Zr,TiO)3 (PZT), PbTiO 3, (Pb,Ba)Nb2O6, Na0.5Bi 4.5Ti4O15, and LiNbO3. The maximum operation temperature is limited by Tc and dielectric loss combined with the level of electrical resistivity. With increased Tc also comes the expense of reduced piezoelectric coefficient (d), being further reduced in non-morphotropic phase boundary (MPB) systems. Recently new high Tc systems with MPBs analogous to PZT have been developed. Predicted by a perovskite crystal structure tolerance factor relationship, compositions based on Bi(Me)O3-PbTiO3, where Me=Sc+3, (Mg+2,Ti+4), etc., exhibit piezoelectric activity compared to PZT, with Tcs greater than 100°C higher, making them promising candidates for high temperature applications.
