Temperature Compensated Piezoelectric Materials

Abstract

From the electrostriction measurements on SBN crystals, it was found that the fourth order electrostrictive coupling terms are not adequate to fully describe the parelectric phase above curie temperature, and hence six rank coupling terms are needed; the electrostrictive coupling terms do not change markedly with cation substitution. Several flux systems have successfully been developed for the liquid phase epitaxy work of SBN compositions. The work is successful, and it is possible to develop epilayers of SBN compositions using barium vanadate flux. SBN crystals grown in our laboratory were used.
