Crystallographic and low frequency dielectric studies were performed on lead-free non-stoichiometric perovskite ceramics of Ba1—xBi2x/3□2x/3TiO3 (0 ≤ x ≤ 0.15) composition. A classical ferroelectric behaviour was shown for x lower than 0.09. A relaxor behaviour appears for higher values of x (0.09 ≤ x ≤ 0.15). The corresponding relaxor characteristics increased as the composition deviated from BaTiO3. Such kind of materials are of interest for environmental-friendly applications, in particular the ceramic with composition corresponding to x= 0.15, whose maximum of permittivity occurs at 280 K, i.e. close to room temperature.
