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.
