Abstract

Barium titanate (BaTiO 3 , BT) grain-oriented ceramics along [110] direction were prepared by a templated grain growth (TGG) method. The [110] oriented BT platelike particles (t-BT) were used as template particles. BT grain-oriented ceramics with higher relative density (D rel ) over 95 %, high degree of orientation along [110] direction (F 110 ) over 80 % and grain sizes around 30 μm were successfully prepared using only the template particles. The relationship between microstructures and piezoelectric constant (d 33 ) was investigated. The higher F 110 was, the higher D rel and the smaller grain size were required for enhancement of the piezoelectric properties.
