Abstract

Multiphase Fe/N nanoparticles were synthesized by means of chemical vapor reaction, the influence of the preparing parameters on the properties of particles was studied carefully during the first nitriding process. The optimum process was determined. Single phase γ'-Fe₄N was prepared by twice-nitriding. Multiphase iron-nitride really transforms γ'-Fe ₄N nanoparticle of single-phase and uniform. Moreover, the mechanism of nanoparticle nucleation and growth, including phase-transformation, was revealed. In addition, the mircograph, particle size, physical phases, schemical constituents and magnetic properties before and after phase-transformation were characterized initially.
