Abstract
The properties of CaBi4Ti4O15 (CBT), CaBi4Ti3.95Nb0.05O15 (CBTN) and CaBi4Ti3.95Nb0.05O15+0.2wt% MnO2 (CBTN–Mn) ferroelectric ceramics with bismuth layer structure were studied. Significant enhancement of piezoelectric coefficient was obtained for CBTN–Mn ceramics (d33=23pC/N), being nearly three times that of CBT counterpart (d33=8pC/N). Together with its high Curie temperature (Tc=790°C), low dielectric loss (tanδ=0.2%), high resistivity (ρ=4.2×106Ωcm at 500°C) and good thermal stability up to 700°C, the CBTN–Mn ceramic is a potential material for high temperature piezoelectric applications.
