Abstract

The ammonium halides present an interesting system for study in view of their polymorphism and the possible internal rotation of the ammonium ion. The static properties of the mixed ionic crystal NH4_4Cl1x_{1-x}Brx_x have been recently investigated, using three-body potential model (TDPM) by the application of Vegard's law. Here, by using a simple theoretical model, we estimate the bulk modulus of their ternary alloys NH4_4Cl1x_{1-x}Brx_x, in terms of the bulk modulus of the end members alone. The calculated values are comparable to those deduced from the three-body potential model (TDPM) by the application of Vegard's law.
