ANGULAR DERIVATIVE OF THE SURFACE-TENSION OF THE (100) FACE OF KCI CRYSTALS

The angular derivative of the surface tension of the (100)face of a KCl single crystal has been determined from the condition of thermodynamic equilibrium at the interface of three phases (the KCl single crystal and two non-miscible liquids), using quasi-equilibrium at the interface of three phases (the KCl single crystal and two non-miscible liquids), using quasi-equilibrium dissolution of a KCl single crystal. It has been established that the force, due to the anisotropic constituent of surface tension, is comparable to the surface tensions at the interface and that it can play a significant role in the thermodynamics of surface phenomena.
