摘要：
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 H-2. 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.
