The organic bindings used were glycerol, PVA (polyvinyl alcohol) and Galactomannan (Adenanthera pavonina). The investigated calcination temperature range was from 773 K to 1073 K. The structural properties were analyzed using differential scanning calorimetry, thermogravimetry, X-ray diffraction and infra-red spectroscopy. The electrical and magnetical properties were investigated using impedance dielectric spectroscopy and Mossbauer spectroscopy. The study of the structural and electrical properties of the lithium ferrites is an important issue in view to their attractive technological properties and low cost of fabrication. This work shows that the binding type, affects significantly the dielectric constant and loss of the LiFe5O8 ceramics. (C) 2011 Elsevier B.V. All rights reserved.
