Saborido-Rey, Fran; Domínguez-Petit, Rosario; Tomás, Javier; Morales-Nin, Beatriz; Alonso-Fernández, Alexandre

9 pages. | Juvenile turbot Scophthalmus maximus were kept in captivity and were fed a prepared food contaminated with 5 levels of seawater-accommodated fuel oil, from 2.4 ± 0.35 to 48.2 ± 2.2 mg/g food. Oil that had been recovered from that released by the tanker 'Prestige' was used. Fish (n = 202) ...

Resumen en español Se busca establecer una metodología para la síntesis de un compuesto fosfato silicoaluminoso, el cual podría encontrar aplicación como electrolito sólido en celdas de combustible. Para alcanzar el objetivo propuesto, se evaluaron tres procesos diferentes de síntesis: (a) proceso hidrotérmico, (b) reacción en fase sólida y (c) vía húmeda. Se emplearon como precursores sílice, gel de sílice, ácido fosfórico, pentóxido de fósforo, fosfato de amonio monobási (mas) co, alúmina y gibbsita. Los polvos obtenidos se conformaron por prensado uniaxial, y se sinterizaron en atmósfera oxidante. La caracterización se llevó a cabo por diferentes métodos: DRX, BET y MEB. Los resultados obtenidos evidenciaron la coexistencia de varias fases: silicoaluminosas, fosfato silicoaluminosas y silicofosfatos. Por otra parte, se observó que la reacción no fue completa durante la sinterización en fase sólida. La investigación evidenció que el proceso de síntesis hidrotérmica es el más idóneo para la obtención de un fosfato silicoaluminoso en pro al conformado de dispositivos con una función de electrolito sólido. Resumen en inglés The main object in the present work is to develop a procedure for the synthesis of an aluminumsilico phosphate compound that could be used as a solid electrolyte in fuel cells. During the synthesis, three different procedures were evaluated: (a) hydrothermal processing, (b) solid-state reaction and (c) humid route. Precursors used were silica, silica gel, phosphoric acid, phosphorous pentoxide, phosphate of monobasic ammonium, alumina and gibbsite. Synthesized powders wer (mas) e prepared as pellets in a uniaxial press and then, they were subjected to thermal treatment in oxidant atmosphere. Materials obtained were characterized by XRD, BET and SEM. Results showed presence of several phases like siliocoaluminun, aluminumsilicophosphate and silicophosphate. Incomplete reaction during solid-state sintering was detected. It was determined that hydrothermal processing was the optimum procedure to obtain an aluminumsilicophosphate compound that could be applied as fuel cell device.
