A novel method for preparing a nickel/YSZ (yttria-stabilized zirconia) cermet has been developed. In the present work, YSZ was deposited onto a substrate containing NiO as an oxygen source by allowing it to undergo a phase reaction in a vapor mixture of ZrCl{sub 4} and YCI{sub 3}. In the initial stage of the reaction, a porous YSZ layer was deposited onto an NiO pellet by chemical vapor deposition (CVD). The porous layer became finer and more gas-tight as the CVD reactions proceeded, and the process then changed from CVD to electrochemical vapor deposition (EVD), resulting in the growth of a dense YSZ layer on the NiO pellet.
