Abstract Ferrochrome nitride was prepared by SHS with Cr2O3， Fe2O3 and Al as experimental raw materials， urea as nitriding medium and NaNO3 as heating agent， respectively. Through the thermodynamic analysis and experimental research， it is proved the feasibility of preparation of ferrochrome nitride by SHS， and the adding amount of NaNO3 is calculated out. The phase composition was analyzed by XRD， and the main metal elements contents were tested by XRF. The mass percent of chromium and iron are 62.70% and 33.25%， respectively. The nitrogen content was determined by azotometer， and the mass percent of nitrogen is 3.42%， which reaches the production standards of ferrochrome nitride.
