Hydriding of intermetallic compound Ti2Ni

Conditions of formation of the Ti2NiH3.3 hydride phase in the reaction of the Ti2Ni intermetallic compound with ammonia and hydrogen have been determined. The products of the reaction of the intermetallide with ammonia in the presence of the NH4Cl activator in the temperature range 100–500°C have been identified. It has been shown that the use of ammonia at temperatures >400°C leads to the formation of titanium nitride and nickel.
