Synthesis of fine α″-Fe16N2 powders by low-temperature nitridation of α-Fe from magnetite nanoparticles

Synthesis of fine α″-Fe16N2 powders by low-temperature nitridation of α-Fe from magnetite nanoparticles

α″-Fe16N2 nanoparticles were produced from starting Fe3O4 powders via hydrogen reduction and low temperature nitridation. Influences of both reduction and nitridation conditions on the synthesis of α″-Fe16N2 were investigated in detail. The magnetic properties of the nitrided products were also stud...
