SUMMARY

The production of Zirconium Oxynitrate from Zirconium (Zr) metal can be achieved through several methods. According to H. Remy's "Lehrbuch der anorganischen Chemie," Zr dissolves effectively in aqua regia, and repeated reduction of the solution with fresh nitric acid (HNO3) can yield ZrO(NO3)2·nH2O. Another method involves dissolving Zr in molten sodium hydroxide (NaOH), which produces hydrogen gas, followed by dilution with HNO3 to avoid chloride contamination. These methods provide viable pathways for synthesizing Zirconium Oxynitrate from Zr metal.

PREREQUISITES
  • Understanding of inorganic chemistry principles
  • Familiarity with aqua regia and its applications
  • Knowledge of the properties and reactions of zirconium
  • Experience with acid-base reactions and hydrolysis
NEXT STEPS
  • Research the properties and applications of Zirconium Oxynitrate
  • Study the preparation and handling of aqua regia
  • Learn about the reactions of zirconium with molten sodium hydroxide
  • Explore techniques for purifying and characterizing ZrO(NO3)2·nH2O
USEFUL FOR

Chemists, materials scientists, and researchers involved in inorganic synthesis or those interested in the production of zirconium compounds will benefit from this discussion.

Anyone know how to produce this from Zr metal? Dissolution in nitric, and HCl have proven a wrong first step. I've been searching all over the internet, and at my library for books/journal articles... No dice.

Any help would be greatly appreciate.
 
Chemistry news on Phys.org
a) Why don't you buy it?
b) Did you try a melt of KHSO4 to dissolve the Zr?
 
Wait, you can buy it? Of course, but if I can make the oxynitrate form from the metal easily, I would do that to save money.

I have not tried #2.
 
I did some reading while at home. My primary source was: H. Remy, Lehrbuch der anorganischen Chemie (oldy but goldy),
Cotton Wilkinson, Advanced inorganic chemistry and
Jander, Hofmann, Qualitative Analyse.

According to Remy , Zr should dissolve easily in aqua regia.
I suppose that reducing the solution repeatedly to dryness adding fresh HNO3 should do the trick to get ZrO (NO3)2 x nH2O.
Alternatively, Zr Remy states that Zr dissolves in molten NaOH under formation of Hydrogen.
You can dissolve the cold melt in diluted HNO3. This has the advantage that no chloride is present.
If you hydrolize some solution and thus deposit fresh ZrO2 (with much hydroxide still), it will readily dissolve in acids before it ages.
