Low sintering temperature of Mg-Cu-Zn ferrites prepared by the citrate precursor method

Abstract

Mg-Cu-Zn ferrite was prepared through a wet synthetic method by a self-combustion reaction directly from a citrate precursor. The as-synthesized powders were sintered at for only 2h. XRD patterns and FTIR spectra confirm the formation of single phase Mg-Cu-Zn ferrite after combustion. To the best of our knowledge, this is the first time that Mg-Cu-Zn ferrite is sintered at such low temperature. The sintering process increased the crystallinity of the solid and the domain sizes.
