In Nitrate, Zirconyl Oxy Nitrate
Hello Folks,
I was going to attempt the following.
US Pat H544 at the bottom
http://www.geocities.com/CapeCanaveral/Campus/5361/chlorate/...
Needed is:
In(NO3)3
Co(NO3)2
Zn(NO3)2
ZrO(NO3)2
I can purchase In, Co. and Zr, and Zn metal on ebay
I have lots of Zinc Sulphate, Cobalt Sulphate, Nitric acid,
common nitrates etc
Where do I start.
Can I make the In(NO3)3 by simply adding In metal to nitric acid?
Can the Co(NO3)2 be made from Cobalt Sulphate (have lots) and some other common nitrates (eg. ammonium nitrate) or do I need a nitrate that is of a
different valency state.
Where do I start with the ZrO(NO3)2 ????????
My chem. is not too hot.
TIA,
Dann2

You can produce cobalt and zinc nitrates by first reacting the sulfate with sodium carbonate producing the metal carbonate as a precipitate. The
insoluble carbonates are then filtered out and reacted with nitric acid making the metal nitrate in solution.
Cobalt nitrate is very hygroscopic, and if you need it crystalline you cannot do this by evaporating a solution of the aqueous nitrate.
Metal carbonates can also be heated with ammonium nitrate to leave the metal nitrate.

Indium will react with nitric acid, but you need to crystallise the nitrate from a strongly acid solution to prevent hydrolysis. So you'll have to use
an excess of acid, and evaporate to isolate the nitrate. The nitrate is very soluble.
Zirconium is worse. Dissolve in aqua regia, add more HNO3 and evaporate to fuming, repeat HNO3/fume a number of times, crystallise from strongly acid
solution. You may be able to start with ZrOCl2 rather than the metal, just fume it down with HNO3 repeatedly.
As already suggested, it's better to go through a carbonate than reacting the metal an HNO3.
I'll see if I can get more information on those nitrates, the books I have on In and Zr are mostly concerned with the metals and their alloys, and
their physical and nuclear properties rather than their chemistry.
