Resumen:
The development of materials for use in hydrogen technology is carried out within a minimalist and ecologist purpose. In such a way, this work presents results on the synthesis and characterization of materials for two different applications related to the use of hydrogen in a clean technology scheme. The materials are obtained by heat treatment of a mixture of intermetallics synthesized by medium energy milling from a mixture of LaNi5 (70% m/m), (La0.25Ce0.52Nd0.17Pr0.06)Ni5 (30% m/m). Samples were characterized during the milling process by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Three stages of milling were identified. Final mixture obtained was thermally treated in Ar atmosphere at 600 ° C during 24 h for the potential application in thermal compression of hydrogen. Similarly, the sample was thermally treated in air at different temperatures for its potential application in hydrogen gross purification.
