General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.
Zirconium(IV) oxide-yttria stabilized (YSZ20) (nanopowder, contains 20 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.

Application

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
  • an electrolyte in the fabrication of solid oxide fuel cells (SOFCs)
  • in the fabrication of zirconia dental implant abutments
  • membranes for micro energy conversion devices
  • a solid acid and a catalyst for catalytic applications
