Abstract
The interaction of the intermetallic compounds ScFe 2 and ScNi 2 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 NH 4Cl 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 ⩾450°C.
