This paper presents the results of the effect of dispersion on the structural-phase state of the material for hydrogen storage of the Mg-Ni-Ce system. X-ray phase analysis and scanning electron microscopy studies have shown that the sequential use of mechanical synthesis and spark-plasma sintering methods ensures the formation of a stable and dense microstructure with a high content of the intermetallic phase Mg2Ni. As a result of dispersion for 1 h, the sintered material was transferred to a finely dispersed state without changing the phase composition. Increasing the duration of dispersion to 2 h led to the formation of large agglomerates and the destruction of the material structure. For the first time, the dispersion technology was applied to materials of the Mg-Ni-Ce system, pre-sintered by spark-plasma sintering.
