“…The effect of the type of precursor salt is evident in Figure 7 where a SEM picture is shown of CuO-CeO 2 film prepared under essentially the same conditions as in Table I but using a different precursor for Ce namely (NH 4 ) 2 Ce(NO 3 ) 6 and at 0.1 M concentration (13). Notice that despite the fact that solution concentration is 0.1 M, no cracking is observed in contrast to Figure 5(left) which should be due to the different type of precursor salt used for Ce that presents a different solution and precipitation behavior than the pure nitrate salt.…”

Fabrication of Thin Electrodic Films by Solution Aerosol Thermolysis (SAT)

We present here results of the application and parameter optimization of the technique of solution spray pyrolysis for the fabrication of electrodic films of the type Cu-CeO 2 and La 0.75 Sr 0.25 MnO 3 (LSM) on dense pellets of the solid electrolyte yttria-stabilized zirconia (YSZ). The first type of electrode combines the properties of a good electronic conductor (Cu) and an efficient catalyst while the second constitutes a typical perovskite exhibiting mixed (i.e. ionic and electronic) conductivity. Both types of electrodes find wide use in ceramic fuel cells, gas sensors and catalytic processes.

Insights into the Effect of Deposition Temperature on YSZ and CGO Thin Films Fabricated by Spray Pyrolysis

2015

View full text Add to dashboard Cite

The Spray Pyrolysis technique was applied to synthesize thin electrolytic films of yttria stabilized zirconia (8 mol% YSZ) onto porous substrates of perovskite La0.7Sr0.3MnO3and gadolinia stabilized ceria (10 mol%GSC) onto dense substrates of YSZ. For both electrolytes the main process parameter that determines the film morphology is the deposition temperature. Aqueous precursor solutions were used for all experiments. The morphology was characterized by scanning electron microscopy and X-ray diffraction.The results indicate that it is possible to obtain adhesive and coherent films of YSZ by tuning the substrate temperature value. For the CGO electrolyte, adhesive but not coherent films were obtained. The substrate material was found to affect the final morphology of the deposited film.
