Abstract

A ferro electric tungsten bronze single crystal of Pb0.33Ba0.70N206 was grown from a melt using the Czochralski technique.the crystal belongs to the tetragonal point group 4mn with the spontaneous polarization parallel to the Iaxis. The room temperature lattice parameters were a=12.50 1 and c=3.995'8.The spontaneous polarization was found to be 0.40 C/m2'C.The Curie transition was 350°C as determined from the temperature dependence of the dielectric constants. The pyroelectric properties were found to be typical of other tetragonal ferro electric bronzes.Dielectric constant '1 1 and piezo electric constant d15 show a strong enhancement from the approach of the tetragonal:orthorhombic morphotropic phase boundary and it is clear that crystals with composition inthe tetragonal phase field closer to this boundary will be of major interest for piezoelectric and electro-optic applications.
