At useful concentrations, it can misbehave unpredictably in traditional
liquid propellant systems. Dry, it's hygroscopic as hell and tends to be
unstable with most heterogenous propellant mixtures. I'll leave a liter jar
of it out on the lab bench from time to time just to see if people are
paying attention.

Subject: [AR] Hydroxylammoniumnitrate (HAN)
Does anyone here have any experience with HAN? It seems like it would be a
very nice low thrust motor option as a monopropellant with good ISP,
density, low toxicity, etc.
Propep seems to underestimate its performance. I get a vacuum ISP
prediction of around 180 s whereas papers (see
https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19960048008.pdf) peg
it much higher (230+ s).
Thanks,
Robert
