Wettability of Carbon Surfaces by Molten Alkali Chloride Mixtures
The wettability of graphite and glassy carbon surfaces by molten alkali chlorides was measured by the sessile drop method. Pure NaCl, KCl and CsCl, binary NaCl-CsCl and NaCl-KCl and ternary NaCl-KCl-CsCl compositions were measured. CsCl was found to be an interfacially active component (at the solid/liquid interface) in both binary NaCl-CsCl and ternary NaCl-KCl- CsCl systems. From the composition dependence of the interfacial energy in the NaCl-CsCl system the hypothesis is made on the possibility of the existence of 3[ 4 ] Cs NaCl complex.
