Zirconium(IV) oxide-yttria stabilizedZrO2 · Y2O3 Nanoparticle /Nanopowder CAS Number : 114168-16-0
Yttria-stabilized zirconia (YSZ) is the most commonly used solid electrolyte for solid oxide fuel cells (SOFCs) and oxygen sensors. YSZ exhibits high oxygen-ionic conductivity while blocking electronic conduction. YSZ particles may be synthesized from yttrium nitrate or isopropoxide by sol gel method. YSZ nanoparticles may be prepared in supercritical water (SCW). YSZ nanoparticles of different sizes with varying % mol of yttria may be obtained by CO2 laser based continuous/pulsed laser vaporization method.
