Abstract

Single crystals of bismuth ferrite-lead titanate (BFPT) were grown using a flux method. Starting from bismuth ferrite, we added lead titanate, to produce a range of compositions within the BiFeO₃-PbTiO₃ solid solution, through to the morphotropic phase boundary (MPB). Using a PbO:Bi₂O₃ flux, and a cooling rate of 0.5°C/h over the temperature range where crystal growth is expected, our aim was to produce highly pure, good size, crack free rhombohedral single crystals. Energy dispersive X-ray analysis (EDX) and scanning electron microscopy (SEM) was used to determine the chemical composition and structure of the crystals, and powder X-ray diffraction (XRD) confirmed the crystal structure.
