Preparation and Characterization of Textured CaBi_4-XLa_XTi₄O₁₅ Ceramics

Abstract:

La3+ doped textured ceramics CaBi_4-xLa_xTi₄O₁₅ 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 CaBi_4-xLa_xTi₄O₁₅ 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.
