General description

Yttria stabilized zirconia (YSZ) is the most commonly used solid electrolyte for solid oxide fuel cells (SOFCs) and oxygen sensors.[1] YSZ exhibits high oxygen-ionic conductivity while blocking electronic conduction.[2] YSZ particles may be synthesized from yttrium nitrate or isopropoxide by sol gel method.[3] YSZ nanoparticles may be prepared in supercritical water (SCW).[4] YSZ nanoparticles of different sizes with varying % mol of yttria may be obtained by CO2 laser based continuous/pulsed laser vaporization method.[5]
Zirconium(IV) oxide-yttria stabilized (YSZ40) (nanopowder, 99.99% trace metals basis, contains 40 mol % yttria as stabilizer) is an oxygen ion conductor with properties such as good ionic conductivity and high physiochemical stability. Its other properties include excellent shock resistance, low thermal conductivity and a high coefficient of thermal expansion.[6][7][8]

Application

Collagen-yttria-stabilized amorphous zirconia hybrid scaffolds may be developed.[2] YSZ thin films may be used as thermal barrier coatings on combustors, stationary and rotating components of gas turbines or diesel engines. 6
YSZ can be used for a variety of applications such as:
  • a thermal barrier coating for the protection and insulation of metal components in gas turbines[7]
  • an electrolyte in the fabrication of solid oxide fuel cells (SOFCs)[9]
  • in the fabrication of zirconia dental implant abutments[10]
  • membranes for micro energy conversion devices[11]
  • a solid acid and a catalyst for catalytic applications[12]
