Wettability of Carbon Surfaces by Molten Alkali Chloride Mixtures

Abstract:

Article Preview

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.
