Abstract: Neste trabalho foram preparados filmes de manganita de lantânio dopados com estrôncio (LSM) nas concentrações de 0, 20 e 40 %at. depositados sobre substratos de silício monocristalino (100) tipo p e de zircônia estabilizada com ítria 8 % em mol (8ZEI) utilizando a técnica de spray-pirólise, tendo como objetivo principal sua utilização como catodo em pilhas a combustível de óxido sólido (PaCOS). Os filmes foram termicamente tratados a 900 ou 1000ºC por duas horas em atmosfera ambiente, tendo sido caracterizados… Show more

“…For the preparation of LSM films, the spray pyrolysis deposition [16] was used, the parameters of deposition and thermal treatment being described in Table 1. Three kinds of precursor solutions were used for the production of La 0.8 Sr 0.2 MnO 3 films: (i) solution of precursor salts (lanthanum, strontium and manganese nitrates); (ii) suspension obtained by the addition of LSM powder (prepared by the amorphous citrate method) to the solution of precursor salts and (iii) suspension obtained by adding commercial LSM powder to the solution.…”

“…Various methods have been used for manufacturing LSM cathodes, including sputtering [14], organometallic vapor deposition [15], spray pyrolysis [16], flame assisted vapor deposition [17] and electrostatic spray [18]. The spray pyrolysis technique is a convenient alternative to the traditional methods, because of the simplicity, low cost, versatility, efficiency and low waste production [16].…”
