I plan to siphon off the P2O5, and flow it through a process chamber. I realize that this will concentrate any impurities present in the H3PO4, and create lifetime issues with whatever material and/or design I choose.
I'm hoping to extend that lifetime. I'm also hoping to win the lottery...
Thanks for the input.
The idea of the process is to heat orthophosphoric acid, and use the P2O5 vapor generated.
I've been using this brochure from the Potash Corp as a reference...
I'm looking for a material that can stand up to high temperature phosphoric acid. And by high temperature, I'm talking up to 500C, atmospheric pressure.
I doubt there's a metal that'll do, but thought I'd ask. Ceramics are a possibility, too. I'm leaning towards quartz right now. There...
I'm going to dilute 85% phosphoric acid down to a 38% solution, and I'm trying to find out how much heat will be generated. I can't find anything more than basic (no pun intended) information in my old chemistry testbook, and I'm not having much luck online, either.
Can anyone give me a clue...
