Zirconium Dioxide

ZrO₂

IUPAC: Zirconium(IV) oxide

CAS: 1314-23-4

Visão geral

Zirconium dioxide is a white crystalline oxide with the highest melting point of any metal oxide. In its cubic form (stabilized with yttrium), it becomes cubic zirconia, a popular diamond simulant in jewelry. It is also an important ceramic material and ion conductor.
