Résumé

PrBaCuO and YBaCuO cuprate materials were prepared from copper, barium peroxide, and yttrium/praseodymium oxide by SHS and standard solid-state synthesis. SHS reactions were carried out using relatively large copper particles (< 63 im) to obtain small product samples (13 mm in diameter). High ambient temperature was used to stabilize a combustion front in the ignited pellets. Explored was the effect of copper particles size, starting density, and ambient temperature on phase evolutions in synthesized materials.
