Ke. Swider et Wl. Worrell, METAL-ORGANIC DEPOSITION OF THIN-FILM YTTRIA-STABILIZED ZIRCONIA-TITANIA, Journal of materials research, 11(2), 1996, pp. 381-386
Mixed-conducting yttria-stabilized zirconia-titania (YZTi) has attract
ive applications in solid oxide fuel cells (SOFC's) and electrocatalys
is, particularly when used as a thin film to reduce its electrical res
istance. Thin films of yttria (12 mol %) stabilized zirconia-titania (
8 mol %) have been prepared using metal-organic deposition (MOD) where
by metal-organic solutions of Zr-, Y-, and Ti-2-ethylhexanoates are sp
un onto suitable substrates. Variables affecting the film surface-morp
hology, chemistry, and crystal structure are examined using scanning e
lectron microscopy (SEM), auger electron spectroscopy (AES), and x-ray
diffraction (XRD), respectively. Uniform, pore-free films having a lo
w carbon content (<1 at. %) are made by sintering on a hot plate at 53
0 degrees C. The effect of thermal cycling on the chemical compatibili
ty and adherence is examined for YZTi films on yttria-stabilized zirco
nia substrates.
