Abstract

A single crystal of (1-x) BiScO3 -x PbTiO3 at x=0.64, which is the morphotropic phase boundary composition for this system, has been investigated utilizing two different types of diffractometry. A total of twenty different reciprocal space maps for different Bragg reflections { hkl } were collected to study their individual splittings. It has been shown that to explain the 2θ splittings observed, a two-phase model is necessary. The best model found consists of either two primitive orthorhombic or two primitive monoclinic lattices and the models previously proposed based on powder diffraction data, consisting rhombohedral or tetragonal symmetries, can be rejected.
