Abstract A versatile platform for the production of metal-oxide composites is reported in this work. A La0.25Ce0.52Nd0.17Pr0.06O2 – 3Ni composite is selected for this study. The composite is fabricated in a two-step method including mechanical milling of the metals/alloys and thermal treatment in air and H2. The mechanism of synthesis includes the structural transformation from cubic to hexagonal of the polymorphs present in the starting La0.25Ce0.52Nd0.17Pr0.06 alloy. The transformation is induced by milling. As a part of the analysis, the enthalpy of formation of the La0.25Ce0.52Nd0.17Pr0.06O2 compound is reported. The work reports a platform for the synthesis of composites. The microstructure of the composites is tunable for the use in different technological applications.
