Abstract

Treatment of intermetallic compounds LaNi5 and SmCo5 with ammonia (initial ammonia pressure 0.6– 0.7 MPa) in the presence of 10 wt% NH4Cl as an activator results in hydrogenation of these compounds or, in the case of SmCo5, in disproportionation to form Sm2Co7Hx. In some cases, the intermetallic matrix decomposes under this treatment.
