Abstract

In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy expansions. our calculated phase diagram agrees well with the experimentally observed phase diagram of NH4F.
