A process for the low temperature, low pressure preparation of the hydride product of ferroalloys of Group IV and Group V metals including niobium, tantalum, vanadium, and silicon and the novel hydride product of ferroniobium.

Process for the preparation of metal hydrides

Ferroniobium, ferrotantalum and ferrovanadium alloys are hydrogenated to facilitate crushing then nitrided, and then acid-leached to produce a soluble iron nitride leachate and a niobium, tantalum or vanadium nitride residue which residue can be denitrided to yield the metal which can be recovered by melting.
