摘要：
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.
