Sodium Orthonitrate

TheChemiKid - 26-12-2013 at 10:17

According to wikipedia, Sodium Orthonitrate can be produced by fusing sodium nitrate and sodium oxide. Here is a link.
I was wondering about the specifics of the reaction.

First: What temperature is needed?
Second: If the temperature is too high, why won't the nitrate decompose?

I don't know what you have been looking at, but that claim in wikipedia actually cites a reference!

No reference to sodium orthonitrate in the merk index or the crc but if tri sodium phospate(Na3O4P) if any thing to go off:

"At the present time trisodium phosphate is made from calcium phosphate in the following manner: The calcium phosphate is digested in an equivalent quantity of sulfuric acid, producing crude phosphoric acid. To this sodium carbonate is added to alkaline reaction, the disodium salt being formed. Finally, a slight excess of caustic soda over that required to form the trisodium salt is added and the solution is allowed to crystallize. It is to be noted that in this process three of the crude materials used are manufactured products-viz., sulfuric acid, sodium carbonate,

n general terms my process consists in digesting the calcium phosphate in the form of a phosphate rock in a water solution of the niter cake until the reaction is complete. To the liquor obtained by this reaction the carbonaceous material is added and the materials are furnaced, producing the trisodium phosphate. 7"

Yay for them! :D
The only thing is you need to pay to see the article, and I don't know how good it is, or even if it answers my question.

WGTR - Thanks!

I know of nobody that ever paid for a scientific article, so I assume you are either being sarcastic, or perhaps this is your first encounter with science, or you never read the forum guidelines. In any case, it is not advisable to boast on ignorance, especially not on a science forum.

No, I wasn't trying to boast.
When I tried to access the reference, it needed me to pay to view it.
