摘要：

Bulk thermal or filament initiated reactions of mixed powders of transition metal chlorides and Sr2N and Ba3N2 produce transition metal nitrides (TiN, ZrN, HfN, VN, V2N) in good yield. The products were characterised by X-ray powder diffraction, SEM/EDAX, FT-IR, microelemental analysis and imaging XPS. The affect of diluting the reaction by the addition of LiCl was used to lower reaction temperatures and in the case of WCl4, and Li3N produced WN. Reaction propagation was investigated by using various mixtures of nitriding reagent (Li3N, Mg3N2, Ca3N2), this was correlated with T-ad,T-s, the maximum adiabatic combustion temperature for salt formation only.
