• A BaBi2Nb2O9 (BBN) powder was synthesized by the double-calcination method at 800 °C, which considerably suppressed the formation of the stable intermediate Ba5Nb4O15 phase. Sintering of the stoichiometric BBN powder at 950 °C for 4 h resulted in the production of densified BBN ceramics with a relative density of 90%. The La3+ substitution was conducted for Ba-deficient BBN powders with nominal compositions of $x=0.03$ and 0.10 in Ba1-xBi2Nb2O9-δ, which were pre-formed by the double-calcination method prior to sintering. The result of the phase identification with XRD, microstructural observation and elemental analysis with SEM and TEM, and dielectric permittivity–temperature relationship that were obtained for the La3+-doped BBN ceramics suggested that the La3+ cations could be predominantly substituted for the Ba2+-sites in the tetragonal BBN structure.
