| Abstract | ||||
| Polycrystalline ferrite BaxTi4-2xFe2xO8 (x= 0.1, 0.3 and 0.5) with hollandite structure was synthesized by the standard double sintering ceramic technique. The changes of sintering time are taken into consideration showing its effect on the behavior of the sample. The electrical properties (real & imaginary parts of dielectric constant, and ac. resistivity) were studied at different temperature as a function of frequencies. The calculated charge carrier mobility indicated that the behavior of the sample is similar to that of semiconductors. The variation of the electric dipole moment with sintering time is observed to be related to ε/. The Seebeck voltage coefficient was studied to confirm the type of charge carriers that participate in the conduction processes. | ||||
