Some electrical and dielectric properties of titanium substituted Li-Zn ferrites

ABSTRACT

The mixed ferrites used have the stoichiometry Li0.35 Zn0.30 Tix Fe2.35-x O4 [where x=0.0 to 0.25 in steps of 0.05] prepared by a ceramic method and sintered at 1150. The a.c. electrical conductivity, the dielectric constant [epsilon '], and dielectric loss factor [epsilon "] of the prepared specimens were measured within the frequency range 105 to 107 Hz and the temperature range 20 to 60. The electronic conductance mechanism was considered involving electronic exchange between Ti4+ and Fe3+, beside ionic conduction, as influenced by parameters such as temperature and frequency
