Preparation and Characterization of Textured CaBi4-xLaxTi4O15 Ceramics

摘要：

La3+doped textured ceramics CaBi4_xLaxTi4O15 were prepared by oriented consolidation of anisometric particle method with tape casting. The orientation was improved by modifying sintering temperature. The doping of La3+in orientated CaBi4-xLaxTi4O15 ceramics increased the dielectric constant. The higher dielectric constant was obtained in the direction which tropism parallels to the electric field. The relationship between dielectric constant and orientation was discussed.
