Anybody have vapor pressure data of any molten salts (say sodium nitrate)?

03 March 2014 1 9K Report

I need vapor pressure data or calculation of vapor pressure for molten salts.

You can use Antoine equation. Parameters needed for each compound can be obtained in handbooks or databases. For example NIST data base is very complete. As an example:

http://webbook.nist.gov/cgi/cbook.cgi?ID=C7447407&Units=SI&Mask=864

for KCl. You can find parameters to apply the Antoine equation to get the vapor pressure at the desired temperatura.
