Abstract
Recently, a new family of oxide-ion conductors based on the ferroelectric perovskite Sodium Bismuth Titanate (Na0.5Bi0.5TiO3, NBT) has been reported. NBT has been investigated intensely as solid electrolytes for Intermediate Temperature Solid Oxide Fuel Cells (IT-SOFCs). This work focuses on the structural and electrical properties of Gadolinium doped Sodium Bismuth Titanate for its possible application as an electrolyte material in SOFCs. Gd doped nanomaterial has been synthesized by mechanical alloying. X-ray diffraction analysis confirms the formation of the rhombohedral phase of Gd doped NBT perovskite with space group R3c. FESEM micrograph confirms agglomerated spherical grains and EDX spectra confirms the existence of the major constituent atoms. Ac conductivity has been found to follow the universal Jonscher’s power law. Structural and electrical characterization of the sample provide its effectiveness as an electrolyte material in SOFCs.
