Structural, Magnetic and Electrical Properties of Highly Dispersed Lithium Iron Spinel Synthesized by Ion Exchange Method
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 1
Abstract
Highly dispersed lithium pentaferrite β-LiFe5O8 was synthesized by ion-exchange method at temperatures up to 120оС. Magnetic structure and specific surface area changes as a function of the ion-exchange reaction duration were analyzed. Obtained β-LiFe5O8 samples have random distribution of lithium and iron ions in oc¬tahedral sublattice of spinel structure that enhances their electrical conductivity. The model that explains of the conductivity dependence on the synthesis duration was proposed. It is expected that the combination of obtained materials electrical and morphological parameters will allow lithium pentaferrite β-LiFe5O8 become an effective cathode material for lithium power sources.
