In the present study, a thermodynamical formulation is developed to determine melting temperature of alkali halides with increasing pressure. The model used estimate at different pressures qualitatively. obtained using Goyal and Gupta thermodynamic equation state. calculations require computed values volume compression, bulk modulus its first pressure derivative varying pressures. It noted from...

Detachment of neutral cations/anions from solid alkali halides can in principle be provoked by donating/subtracting electrons to the surface of alkali halide crystals, but generally constitutes a very endothermic process. However, the amount of energy required for emission is smaller for atoms located in less favorable positions, such as surface steps and kinks. For a corner ion in an alkali ha...
