THE ELECTROCAPILLARY PHENOMENA ON SOLID GOLD IN BINARY MELTS OF STRONTIUM AND CESIUM CHLORIDES

The free energy of the surface of solid gold in binary molten mixtures of strontium and cesium chlorides is determined as a function of the temperature, salt-phase composition, and electric potential on the bas is of changes in the weight of a freely hung electrode semi-immersed i n electrolyte. Variations in the shape of the electrocapillary curve; the potential dependence of the electric charge density; and the conce ntration dependences of the potential of zero charge, surface energy a nd contact angle are utilized for elucidating the nature of interactio n of the ionic-melt components between themselves and the gold electro de surface and the nature of adsorption of the salt-phase ions at the interface.
