View Product Description

Atomic level zirconia project

This project adopts zirconium oxychloride as raw material, dissolved into an aqueous solution and extracted with TBP-HNO₃-HCL system. Zirconium and hafnium are separated, sedimentation and calcined, and Hafnium free zirconia and hafnium dioxide are formulated separately.

Extraction

In the extraction process, TBP is used as the extractant, the chemical formula is (C4H2O)PO is used as the diluent of kerosene, and the organic phase is acidified with 6mol nitric acid, so that the acidity of the organic phase reaches saturation, and then extracted with the material liquid, Zr enters the organic phase, and Hf remains in the water phase, so as to achieve the purpose of separating Zr and Hf. The chemical reaction of the extraction process is:

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

Calcination

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
