Abstract

Tungsten bronze single crystals in the Pb1 Ba Nb906 system were grown from a melt using the Czochralski technique. The dielectric, piezoelectric and pyroelectric properties were determined. The dielectric constant KA and piezoelectric coefficient d15 showed a strong enhancement upon approaching the tetragonal:orthorhombic morphotropic phase boundary as predicted by thermodynamic phenomenology. It is clear that crystals with a composition in the tetragonal phase field near this boundary will be of major interest for various piezoelectric device applications.
