Abstract

Drop solution calorimetry in high-temperature oxide melts has been shown to be very useful to study the energetics of nitride formation. This methodology was used to determine the enthalpies of formation from the elements of binary and ternary nitrides in the Ce/Mn/N system. The resulting values in kJ mol^-1 are; ΔH_f^o (CeN) = -340.19 ± 6.80, Δ(H_f^o (Mn₃N_1.95, η-Mn₃N₂ type) = -192.68 ± 7.57, ΔH_f^o (Mn₆N_5.40, 0-Mn₆N₅ type) = -430.80 ± 10.93 and ΔH_f^o (Ce₂MnN₃) = -928.18±9.46. The results show the role of inductive effects in Ce₂MnN₃ leading to a higher energetic stability compared to binary components.
