Such a process occurs when zirconium dioxide is stabilized by metal oxides with cations of a lower valence than that of zirconium. Thus, when yttrium oxide is introduced, there is one oxygen vacancy per two introduced trivalent Y 3+ ions. This contributes not only to the possibility of stabilizing the high-temperature modification of …

Ceramic; Oxide; Zirconium Oxide. Material Notes: Property data is typical for commercially available yttria stabilized zirconia ceramics, and varies with processing and exact composition. The yttrium oxide addition stabilizes the high temperature tetragonal zirconia phase and prevents transformation to the room temperature stable monoclinic phase.
Yttrium stabilized zirconia (YSZ) used as the state-of-the-art electrolyte for solid oxide fuel cells (SOFCs) requires high temperature (over 800 °C) to realize sufficient oxygen ion conductivity. Thus, the high operational temperature is the main restriction for the commercial process of YSZ-based SOFCs.
