PHASE TRANSITIONS, cilt.72, sa.4, ss.351-360, 2000 (SCI-Expanded)
In this study using a mean field model we calculate the phase line equations for the beta-delta, beta-gamma and gamma-delta phase transitions in the NH4BrxCl1-x system. We then fit our phase line equations to the experimentally observed T-X-Br phase diagram for this system. Our calculated phase diagram agrees well with the observed one for the NH4BrxCl1-x system.
