摘要：

Bismuth sodium titanate, (Bi1/2Na1/2)TiO3 (BNT)-based solid solution, a(Bi1/2Na1/2)TiO3-bBaTiO(3)-cBiFeO(3), [BNBTF(100a/100b/100c)], was studied for its dielectric, ferroelectric and piezoelectric properties, as a new group of lead-free piezoelectric ceramics. Curie temperatures, T-c, of the BNBTF ceramics shift to the higher temperature with an increasing amount of modified Bi ion, and temperature dependence of the resonance frequencies,f(r), is smaller with increasing amount of modified BiFeO3.
