Abstract
Recently, lead-free piezoelectric materials are intensely studied due to being environmentally friendly. Among them, sodium bismuth titanate (Na1/2Bi1/2TiO3, or NBT) and its various solid solutions have been drawing special attention as a new candidate for their lead based counterparts. There is a great demand for reducing the adverse effect of lead. In this study, Hafnium (Hf^4+) or Zirconium (Zr^4+) doped grain oriented (Na1/2Bi1/2)TiO3 (NBT) ceramics with 100 orientation were fabricated by Templated Grain Growth (TGG) method using anisotropically shaped SrTiO3 template particles. Hf^4+ or Zr^4+ doped NBT ceramics were characterized by using X-Ray diffraction (XRD), scanning electron microscopy (SEM), polarization and electromechanical measurements.
