✦ Synopsis

Ahattract

-Activity data for NaCI, AlCI, and NaAICl, in basic Nail-AICI, melts are derived from emf measurements. Literature values for the total vapour pressure are interpreted in terms of partial pressures of the gaseous species AICI,, Al,Cl,, and NaAlCl,. A possible contribution of small amounts of the dimer Na2A12ClS(g) is discussed. Thermodynamic data are derived for the molten mixture and for the corresponding vapour phase. Interaction between the melts and silica or alumina container materials is considered.

Emf measurements in the formation cell AlJAlCl,(I), NaCI(l)ICI, were carried out at different mol fractions of AlCl, in the range 0 c x~,~t, c 0;5. The activity of AICl, increases strongly as the equimolar composition is approached, indicating the presence of a fairly stable AICl; complex ion in suc
