PHASE TRANSITIONS, cilt.72, sa.4, ss.299-308, 2000 (SCI-Expanded)
We calculate here the phase line equations using the mean field theory for the liquid-solid I-solid II phases in the ammonia close to the melting point. Our calculated phase line equations have been fitted to the experimental data. Our calculated phase diagram agrees very well with the experimentally obtained P-T phase diagram from the literature.
