Sintering Time Effect on the Electrical Properties of Barium Titanium Ferrite
El-Refai, amna;
Abstract
Polycrystalline ferrite BaxTi4_2xFe2xOs(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 I. The Seebeck voltage coefficient was studied to
confirm the type of charge carriers that participate in the conduction
processes.
