Textured 0.94Na 0.5 Bi 0.5 TiO 3 –0.06BaTiO 3 (NBT–6BT) ceramics were fabricated by templated grain growth (TGG) using anisotropically shaped Na 0.5 Bi 0.5 TiO 3 (NBT) templates. Platelet NBT was synthesized by the topochemical technique, using precursor Na 0.5 Bi 4.5 Ti 4 O 15 (NBIT). The NBT particles have an average length of 10–15 μm and a thickness of 1 μm, which are suitable templates for obtaining textured ceramics (especially NBT‐based ceramics) by the TGG process. This study revealed that the NBT templates are effective in inducing grain orientation in NBT–6BT ceramics. For NBT–6BT ceramics textured with 5 vol% NBT templates, a Lotgering factor of 0.87 and a d 33 of 299 pC/N are given.
