# Is there a phase diagram available for hydrogen fluoride?

Has a phase diagram for hydrogen fluoride been published in an article on the internet or in a book ?

Or is there a table for HF for different pressures up to 100 atm. and temperatures up to 500$$⁰$$ C ?

Or, even better, is there a calculator for HF, like this one for steam ?

• I checked Reaxys but couldn't really find anything on it. If I find some time I could check the Gmelin in our library tomorrow, they might have it. – Justanotherchemist Feb 2 '20 at 14:04
• Might be offtopic here but of course there is an interesting difference as HF is the only common acid that will form H-bonding bridges to itself rather than to water. Still the H-bonding donating and accepting effects are different for H2O and HF which leads to different properties. But I'll check tomorrow. – Justanotherchemist Feb 2 '20 at 14:48
• Why on Earth are you interested in HF to 100 atm. and at 500°C ? HF is such a dangerous compound.. Who would like to heat up to 500°C a sample of gaz like HF compressed to 100 atm ? – Maurice Feb 2 '20 at 15:04
• @Maurice I can imagine you wondered ! I would like to investigate if HF could be a usefull lifting gas in the atmosphere of Venus with temperatures up to 462$⁰$ C and pressures up to 92 atm. – Cornelis Feb 2 '20 at 15:10
• Sounds like a terrible idea anyway. Normal air is enough of a lifting gas out there. – Ivan Neretin Feb 2 '20 at 15:28
