ammonium-sodium-phosphate
anyone know any uses for this chemical? Possibly synthesizing phosphoric acid?

Also for making phosphorus, heating some forms results in loss of ammonia and cyclization to sodiumhexametaphosphate which is in my experience the
easiest phosphate to reduce.

What exactly do you mean when you talk about reducing phosphates. Are you refering to reduction of a phosphate salt into phosphorus. How exactly would
you make phosphorus from ammonium sodium phosphate? I assume you would need a blast furnace or something.

Yes and no, depends on what you're reacting...
Go read the phosphorous thread.

Sodium hexametaphosphate begins to react with aluminum at around 500C and is essentialy complete by 900C as I remember. So the reduction is fairly
easy. Converting to sodiumhexametaphosphate from ammonium sodium phosphate, I don't remember the details.

The original salt used to make Phosphorus was 'microcosmic salt' from evaporated decomposed urine, which was the sodium ammonium hydrogen
phosphate. NH4·NaHPO4·4H2O
I have seen sites that list it without the hydrogen.

How hot Do I have to get the ammonium sodium phosphate in order for the NH3 gas to be liberated? Also, does reduction of phosphorus need to be done in
an inert atmosphere?

If you don't know the answer to that one, then you don't need to be playing with the reduction of phosphorus.
And to answer your question, yes.

Ya I knew that, don't know what I was thinking. But I re read the phosphorus thread, and it reminded me how dangerous this procedure is, and that
I will probably never try it. I still would like to know at what temp ammonium sodium phosphate liberates the NH3 gas. Probably use my sodium
phosphate for a phosphoric acid synth.
