How Can Zirconium Oxynitrate Be Produced from Zr Metal?

[Bakery87]

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.

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.

I can understand your frustration in trying to produce zirconium oxynitrate from Zr metal. It is important to note that the production of this compound is a complex process and requires a thorough understanding of the chemical reactions involved.

One possible approach to producing zirconium oxynitrate is through a two-step process. The first step would involve the oxidation of Zr metal using a strong oxidizing agent such as nitric acid. This will produce zirconium oxide (ZrO2).

In the second step, the zirconium oxide can be reacted with a mixture of nitric and hydrochloric acid to form zirconium nitrate (Zr(NO3)4). This can then be further reacted with ammonia to produce zirconium oxynitrate (ZrO(NO3)2).

It is important to carefully control the reaction conditions, such as temperature and concentration, to ensure the desired product is obtained. Additionally, using high purity Zr metal and reagents can also improve the yield and purity of the final product.

I would also suggest consulting with experts in the field or reaching out to research institutions that specialize in zirconium compounds for further guidance. I hope this information helps and wish you success in your research.
