Resumen:
75BaTiO3?(25 - x)BiMg0.5Ti0.5O3?xNaNbO3(x = 0?0.2) ceramics were obtained by conventional solid-state reaction method. X-ray diffraction patterns of the samples showed the formation of cubic structure.No evidence of secondary phase was found within the detection limit of XRD facility which was in agree-ment with the Raman spectra of all the samples. Temperature dependence of relative permittivity anddielectric loss for the sample with x = 0.10 showed a temperature stable relative permittivity of 840 ± 15% over the temperature range 62 to 192 °C and dielectric losses
