Özet
In this study, Hafnium or Zirconium doped grain oriented (Na1/2Bi1/2) TiO3 (NBT) ceramics with < 001 > orientation were fabricated by Templated Grain Growth (TGG) method using anisotropically shaped SrTiO3 template particles. These molten salt synthesized SrTiO3 platelets were tape cast with calcined NBT powder, and sintered at 12000 degrees C for 6 h. Texture fractions up to 70% have been obtained. Also, electromechanical properties of Hf4+ and Zr4+ doped NBT ceramics under electrical bias were studied.
