A. Mineshige et al., PREPARATION OF YTTRIA-STABILIZED ZIRCONIA MICROTUBE BY ELECTROCHEMICAL VAPOR-DEPOSITION, Journal of the American Ceramic Society, 78(11), 1995, pp. 3157-3159
A microtube of yttria-stabilized zirconia of ca. 100 mu m was formed o
ver a surface-oxidized nickel wire with a diameter of 100 mu m by elec
trochemical vapor deposition using zirconium tetrachloride and yttrium
trichloride as metal sources, and nickel oxide as an oxygen source fo
r the reaction. The YSZ-coated wire was then immersed in aqueous 11.5
mol . L(-1) hydrochloric acid to dissolve the nickel and nickel oxide,
and a microtube of .8 mol% yttria-stabilized zirconia with a cubic cr
ystal structure was obtained. The surface of the microtube was rough,
but was pinhole-free, from SEM observation. The thickness of the zirco
nia layer was about 3 mu m.
