Temperature Compensated Piezoelectric Materials

Abstract

A literature survey of the known tungsten bronze structural family has been completed and compiled. A phenomenological model based on the Gibb's energy functions to explain the nature of temperature compensation in the bronze family has currently been developed. This work has been extended to specific bronze phases such as the tetragonal SBN and the orthorhombic PBN. Several flux systems have successfully been established for the liquid phase epitaxy (LPE) work of the SBN compositions. The LPE work has recently been initiated on SBN phases using substrates and barium vanadate as flux. The SBN single crystals grown in our laboratory showed exceptionally strong piezoelectric activity in all poled samples of SBN crystals.
