Studies of the structural and electrical properties of lithium ferrite (LiFe₅O₈)

Abstract

A lithium ferrite with the general formula LiFe5O8 was prepared by a new variation of the ceramic method, in which high-energy mechanical milling and calcinations of Li2CO3 and Fe2O3 were used. In this paper, we present a study of the structural and electrical properties of this ceramic phase. We also investigate the effects of the use of galactomannan as a new binding option as compared with a traditional binding material like glycerol.

Variation of Dielectric and Electrical Properties of Zr-Substituted Lead Calcium Iron Niobate with Temperature and Frequency

“…23,31 At higher frequencies, the plots of Z¢ show the frequency independent behavior, which is due to the possible release of space charge and a consequent lowering of the energy barrier properties. [32][33][34][35][36] There is a linear decrease in magnitude of Z¢¢ with increase in frequency for y = 0.00 at low temperatures (up to 473 K), which is similar to the plots of M¢¢ and can be explained in a similar way. It suggests that relaxation species are immobile defects.…”

Dielectric investigation of the Sr3WO6 double perovskite at RF/microwave frequencies

“…Where j ¼ uC 0 Z* and the vacuum capacitance is represented C 0 and j ¼ OÀ1. 15,16 Nyquist diagrams were obtained by tting using the Eisanalyser soware.…”

Study of the temperature and organic bindings effects in the dielectric and structural properties of the lithium ferrite ceramic matrix (LiFe5O8)

“…The values of ε of the samples with Gal are always the lowest. Therefore the dielectric loss, which increases with increasing temperature and decreases with increasing frequency, presents the lowest value for the sample containing Gly [30]. …”

“…Several researchers have studied the frequency and temperature dependence of the dielectric properties of LiFe 5 O 8 [25][26][27][28][29]. However, there are few studies dealing with the effect of the bindings on the structural and electrical properties of the lithium ferrite ceramic [30]. In this study, LiFe 5 O 8 ceramics were prepared using the conventional ceramic method.…”
