Zirconium Oxide, with the chemical formula ZrO₂ and CAS Number 1314-23-4, is a versatile white crystalline powder. It is also commonly referred to as Zirconia, Zirconium Dioxide, or Zirconium(IV) Oxide.
It is insoluble in water and slightly soluble in acids, with excellent resistance to thermal shock, corrosion, and wear.
Zirconium Oxide is prized for its exceptional thermal stability, mechanical strength, chemical inertness, and biocompatibility.
