Abstract

The properties of CaBi₄Ti₄O₁₅ (CBT), CaBi₄Ti_3.95Nb_0.05O₁₅ (CBTN) and CaBi₄Ti_3.95Nb_0.05O₁₅ + 0.2 wt% MnO₂ (CBTN-Mn) ferroelectric ceramics with bismuth layer structure were studied. Significant enhancement of piezoelectric coefficient was obtained for CBTN-Mn ceramics (d₃₃ = 23 pC/N), being nearly three times that of CBT counterpart (d₃₃ = 8 pC/N). Together with its high Curie temperature (T_c = 790 °C), low dielectric loss (tanδ = 0.2%), high resistivity (ρ = 4.2 × 10⁶ Ω cm at 500 °C) and good thermal stability up to 700 °C, the CBTN-Mn ceramic is a potential material for high temperature piezoelectric applications.
