The synthesis of Fe<SUB>2</SUB>N powder from FeC<SUB>2</SUB>O<SUB>4</SUB> powder and their thermal decomposition behavior were studied, and their magnetic properties were investigated. FeC<SUB>2</SUB>O<SUB>4</SUB> powder, which is a starting material of iron nitride, was prepared by the precipitation method in ethanol solvent (FeCl<SUB>2</SUB>aq.-H<SUB>2</SUB>C<SUB>2</SUB>O<SUB>4</SUB>⋅EtOH), consequently fine powder was obtained. Fe<SUB>2</SUB>N powder was prepared by the thermal decomposition of fine FeC<SUB>2</SUB>O<SUB>4</SUB> powder under NH<SUB>3</SUB> gas flow at 410°C, and the pyrolysis temperature was lower than that of FeC<SUB>2</SUB>O<SUB>4</SUB> made from water solvent (FeCl<SUB>2</SUB>aq.-(NH<SUB>4</SUB>)<SUB>2</SUB>C<SUB>2</SUB>O<SUB>4</SUB>aq.). When the Fe<SUB>2</SUB>N powder was heated in air and under Ar gas flow, the pyrolysis started at 150°C and 350°C, respectively. Fe<SUB>3</SUB>N single phase was obtained by pyrolysis of Fe<SUB>2</SUB>N powder at 400°C under Ar gas flow, and iron nitride transformation from paramagnetism to ferromagnetism was caused.
