Preparation of Grain-Oriented Ceramics with Bismuth Potassium Titanate-Barium Titanate and their Piezoelectric Properties

Abstract:

Bismuth potassium titanate ((Bi_1/2K_1/2)TiO₃: BKT) powder were prepared using bismuth oxide (Bi₂O₃), potassium hydrogen carbonate (KHCO₃) and titanium oxide (TiO₂) raw materials. Barium titanate (BaTiO₃: BT) platelike particles oriented along [110] direction were used as template particles. Barium titanate-bismuth potassium titanate (BT-BKT) ceramics had a tetragonal phase at -100 °C. The main composition was fixed to BKT 30 molar% because the Curie temperature (T_C) was well above 200 °C at BKT 30 molar%. The orientation of [110]-oriented BT-BKT ceramics (BKT 30 molar%) was 54.6 %.
