Product Name:Zirconium dioxide
CAS Number:1314-23-4
Molecular formula:O2Zr
Molecular Weight:123.22

Zirconium oxide occurs in nature as mineral baddeleyite. Ore is mined from natural deposits and subjected to concentration and purifcation by various processes. The oxide, however, is more commonly obtained as an intermediate in recovering zirconium from zircon, ZrSiO4 (See Zirconium, Recovery).
Also, the oxide may be prepared in the laboratory by thermal decomposition of zirconium hydroxide or zirconium carbonate:
Zr(OH)4 → ZrO2 + 2H2O
Zr(CO3)2 → ZrO2 + 2CO2

Steps:

Synthesis of ZrO(OH)2 and ZrO2

Concentrated NH₄OH was added to an aqueous solution of ZrOCl₂.8H₂O (100 gL^-1), and the pH of the solution was adjusted to 9 to 10 with vigorous agitation.
The generated emulsion was aged for 24 hours, filtered, and washed thoroughly with water.
The obtained solid precipitate was dried at 100° C. overnight to obtain ZrO(OH)₂.
The obtained ZrO(OH)₂ was calcined in air at 500° C. for 5 hours to prepare ZrO₂.
