Synthesis and characterization of fine particle ZnFe2O4 powders by a low temperature method

Fine particle ZnFe2O4 powders have been prepared by the low temperature process without any intermediate phase formation. The precursor was prepared and fired at low temperature to form the desired product. Very pure, fine, monophase ZnFe2O4 powders were obtained by the calcination of the precursor in air to about 450°C for 2 h. The IR and EPR characteristics of the fine powders are presented and discussed in terms of the particle size effect.
