The interaction of the intermetallic compounds ScFe2 and ScNi2 with ammonia was investigated at an initial pressure of ammonia of 0.6-0.8 MPa in the presence of 10 mass% (from the quantity of intermetallide entered in reaction) of NH4Cl as a process activator. The possibility of obtaining both crystalline hydrides of the intermetallic compounds and amorphous products of a reaction in a high-dispersed state was shown at various temperatures. It has been established that the decomposition of the intermetallides in ammoniacal medium occurs at greater than or equal to 450 degreesC.
