Abstract

Barium titanate (BaTiO₃, 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 (F₁₁₀) over 80 % and grain sizes around 30 μm were successfully prepared using only the template particles. The relationship between microstructures and piezoelectric constant (d₃₃) was investigated. The higher F₁₁₀ was, the higher D_rel and the smaller grain size were required for enhancement of the piezoelectric properties.
