The reactivity of lattice nitrogen in filled beta-Mn structured Co2Mo3N and eta-carbide structured Co3Mo3N and Fe3Mo3N was investigated under 3:1 H2/Ar at temperatures up to 900 degrees C. It was found that lattice nitrogen in Co3Mo3N was reactive, while Co2Mo3N was stable up to 800 degrees C. Furthermore, upon H2/Ar treatment at 900 degrees C, the Co2Mo3N, Co3Mo3N, and Fe3Mo3N phases decomposed, indicating that both metal composition and phase have an influence on the bulk lattice nitrogen reactivity of the ternary nitrides.
The reactivity of the lattice nitrogen in the filled beta-Mn structured Co2Mo3N and the eta-carbide structured Co3Mo3N and Fe3Mo3N has been investigated under 3:1 H-2/Ar at temperatures up to 900 degrees C. The lattice nitrogen in Co3Mo3N was found to be reactive, as reported previously, whereas Co2Mo3N was shown to be stable up to 800 degrees C. Upon H-2/Ar treatment at 900 degrees C, the Co2Mo3N, Co3Mo3N and Fe3Mo3N phases decomposed. These results suggest that both metal composition and phase have an influence on the bulk lattice nitrogen reactivity of the ternary nitrides.
