FIELD: inorganic synthesis catalysts.
SUBSTANCE: invention provides ammonia synthesis catalyst containing ruthenium as active ingredient supported by boron nitride and/or silicon nitride. Catalyst can be promoted by one ore more metals selected from alkali, alkali-earth metal, or rare-earth metals. Ammonia synthesis process in presence of claimed catalyst is also described.
EFFECT: increased temperature resistance of catalyst under industrial ammonia synthesis conditions.
