The high temperature dielectrics properties of unfilled tungsten bronze ceramics, Ba4SmFe0.5Nb9.5O30, were studied. The temperature dielectric properties and the variable temperature XRD data, in addition to the XPS data indicated that BSFN ceramics have no phase changes from 25 °C to 450 °C; the high temperature relaxation behaviour around 350 °C is closely related to the oxygen defects. Frequency dependence of temperature electrical conductivity relaxation of Ba4SmFe0.5Nb9.5O30ceramics was well fitted by the Arrhenius relationship with Ea~ 0.65 eV.
