[en] Full text: The polycrystalline sample of Ba₅DyTi₃V₇O₃₀ ceramics was prepared by a mixed-oxide method at 1000 deg C (sintering temperature). The formation of the compound was confirmed using an X-ray diffraction technique at room temperature. Scanning electron micrograph of the material showed uniform grain distribution on the surface of the sample. Detailed studies of dielectric properties of the compound as a function of temperature (30 deg-400 deg C) at different frequencies (10³-10⁶Hz) suggest that the compound has a dielectric anomaly of ferroelectric to paraelectric type at a temperature ∼440 deg C, and exhibits diffuse phase transition. Electrical properties of the material were analyzed using a complex impedance technique. The Nyquists plot showed the presence of grain boundary effects in the material. Studies of electrical conductivity over a wide temperature range suggest that the compound exhibits the negative temperature coefficient of resistance behavior. The ac conductivity spectrum was found to obey Jonscher's Universal power law
