Miscibility Gaps in Fused Salts

Abstract

Molten mixtures of HgCl2, HgBr2 and HgJ2 with alkali nitrates have been investigated. Two liquids regions occur in the following systems: HgCl2 + (Li, Na) NO3, HgBr2 + (Li, Na, K, Rb) NO3 and HgJ2 + (Li, Na, K, Rb, Cs) NO3. The ability of demixing progressively increases in the sense Cs → Li and Cl → J. Moreover the composition squares of the systems Na, Hg/NO3, Cl and (Na, K, Rb), Hg/NO3 Br have been partially drawn.
