Structural and Electrical Characterization of LaSrAl_1-xMg_xO_4-δ Layered Perovskites Obtained by Mechanical Synthesis.

ABSTRACT: This work presents the structural and electrical characterization of K₂NiF₄-type layered perovskites of LaSrAl_1-xMg_xO_4-δ composition to be used as oxide-ion electrolytes for a solid-oxide fuel cell (SOFC). These perovskites were prepared by mechano-chemical synthesis (ball milling), an alternative to traditional synthesis methods such as citrate-nitrates and solid-state reaction. With these methods, two things are avoided: first, the use of nitrate salts, which are more environmentally harmful than oxide precursors, and second, it saves the series of long thermal treatments associated with solid-state reactions. After grinding the precursors, nanometric particles were obtained with a combination of crystalline regions and amorphous reg
