A microtube of yttria-stabilized zirconia of ca. 100 {micro}m diameter was prepared. A yttria-stabilized zirconia film was formed over a surface-oxidized nickel wire with a diameter of 100 {micro}m by electrochemical vapor deposition using zirconium and tetrachloride and yttrium trichloride as metal sources, and nickel oxide as an oxygen source for the reaction. The YSZ-coated wire was then immersed in aqueous 11.5 mol {center_dot} L{sup {minus}1} hydrochloric acid to dissolve the nickel and nickel oxide, and a microtube of 8 mol% yttria-stabilized zirconia with a cubic crystal structure was obtained. The surface of the microtube was rough, but was pinhole-free, from SEM observation. The thickness of the zirconia layer was about 3 {micro}m.
