Zro2 Equipment/ Zirconia Plant/ Zirconium Oxide Production Line/ Zirconium Dioxide Project

Extraction

ZrO²⁺ +2H⁺ +2NO3^- +CI^- +2TBP----Zr(NO₃)₂CI₂ ^.2TBP
ZrO²⁺ + NO₃^-+ CI^- + 2TBP ---- Zr(NO₃)CI ^.2TBP

The production of zirconium dioxide (hafnium dioxide) from zirconium tetrachloride requires dissolution, extraction separation and precipitation, and finally calcination.

ZrCI₄ + H₂O ------ZrOCI₂ + 2HCI
HfCI₄ + H₂O ------HfOCI₂ + 2HCI


ZrO²⁺ +2OH+HO₂ ------- Zr(OH)₄
Zr(OH)₄ After calcination into semi-finished products ZrO₂
Zr(OH)_4------ ZrO₂ + HO₂ calcination temperature 900ºC
