Abstract:
Abstract In this study using a mean field model we calculate the phase line equations for the β-δ, β-γ and γ-δ 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.Keywords:

The phase diagram of the LaF 3-NaF system is optimized by using the new modified quasichemical model in the pair-approximation for short-range ordering and calculated with CALPHAD (Calculation of Phase Diagram) technique. This model was used to describe the Gibbs energies of liquid phase in this system. A set of thermodynamic functions has been optimized based on an interactive computer-assisted analysis. The calculated phase diagram and optimized thermodynamic parameters are thermodynamically self-consistent.
