Fully Stabilised Zirconia. Yttria fully Stabilized Zirconia (with 8 mol% Y 2 O 3) is a commonly used and well characterized ceramic electrolyte material YSZ8 is used as a Solid Oxide Fuel Cell (SOFC) electrolyte membrane in solid oxide stacks and as a component in composite cathodes or cermet anodes.

As far as we know the investigations on the thermal properties have been focused on 34YPSZ However the thermal properties for the fully stabilized zirconia ce ramics doped with high content of yttria have been studied insufficiently Particularly for the cases temperature is higher than 1 000 ºC.
The high temperature cubic phase of zirconia is stabilized down to room temperature by a cation solid solution [ 4 5 ] TiO 2 –ZrO 2 solid solution ceramics have been reported with TiO 2 contents less than 40 mol% [ 6 ] In addition previous studies have reported on TiO 2 doped YSZ ceramics [ 7 – 11 ].

Fully Stabilized Zirconia is applied in hightemperature applications that require strong thermal shock resistance fracture toughness and superior corrosion resistance Additionally Fully Stabilized Zirconia has the unique capability to allow oxygen ion transporting meaning only oxygen ions can pass through its structure.
Zirconia is commonly blended with either MgO CaO or Yttria as a stabilizer in order to facilitate transformation toughening This induces a partial cubic crystal structure instead of fully tetragonal during initial firing which remains metastable during cooling.
