Structural Properties and D.C. Resistivity of Li-Zn-Ti Ferrites.

In this paper we report influence of titanium substitution on the structural properties and d.c. conduction behavior of Li-Zn ferrites. The samples having the compositional formula Li[sub 0.45+0.5t]Zn[sub 0.1]Ti[sub t]Fe[sub 2.45-1.5t]O[sub 4] with t varying from 0 to 1.2 in steps of 0.2 were prepared by the conventional dry ceramic method. XRD analysis showed all the samples to be single phase spinel and the lattice parameter was found to increase with increasing t. D.C. resistivity increases with Ti concentration. The possible mechanisms involved are discussed. [ABSTRACT FROM AUTHOR]
