ABSTRACT:
A method is disclosed for preparing and recovering metal nitrides from their ferrometal alloys and nickel metal alloys. Exemplary steps of the process involve niobium nitride prepared from ferroniobium alloys (FeNb) which are first hydrided to provide a friable, comminutable product which is then nitrided under conditions which form distinct phases of iron nitride and niobium nitride respectively.
