Textured poly crystalline barium dititanate BaTi2O5 (BT2) ceramics with a preferred < 010 > orientation were synthesized by laser rapid solidification method, with a CO2 laser. The < 010 > orientation of the BT2 is along the laser incident direction, and the orientation factor (f) and relative density of the unannealed BT2 sample are 0.40 and 96.2%, respectively. The two quantities increase with increasing annealing time, and reach the maximum values of 0.42 (annealed at 1,000 degrees C for 12 h) and 97.5% (annealed at 1,000 degrees C for 24 h), respectively. The images of scanning electron microscopy reveal that the BT2 are composed of flake-like microstructures with the maximum thickness of 20 mu m and dimension of 0.6 mm, which are parallel to the laser incident direction. The measured Curie temperature (T-c) and the maximum dielectric constant (epsilon(max)) are 443 and 6,000 degrees C, respectively.
