| Outline of Final Research Achievements |
Fe (acac) 3, or Fe (Cp) 2 was used as Fe source, 25% aqueous ammonia, hydrazine monohydrate, N, N- Dimethylhydrazine, 70% ethylamine aqueous solution, or 40% methylamine aqueous solution was used as N source. The raw material was placed in a hot wall type batch reactor, then supercritical carbon dioxide was introduced, and the mixture was heated to the set temperature and reacted at a predetermined pressure and time.
From the XRD results of the dried samples with ten different combinations of two different Fe sources and five N sources, Fe16N2 was yielded most by a combination of Fe(Cp)2 and a 40% methylamine aqueous solution. Using this combination by changing the temperature, pressure and reaction time, the main components of the sample prepared were Fe(Cp)2, Fe2O3, and Fe16N2. Among them, 200°C, 13 MPa, and 1.5 h was the most suitable for Fe16N2 production. However, the reaction time was 5 h, oxidation and nitridation was confirmed.
