Classification of Stability for Tetrahedral Halocomplexes in Molten Salt Mixtures

摘要

We show that a priori atomic parameters (valence electron orbital radii) allow classification of the stability of tetrahedral halocomplexes formed by polyvalent s-p metals in molten mixtures of their halides with alkali halides. The present classification scheme for liquid mixtures parallels previous structural classifications for pure components in solid and molecular phases and is also essentially consistent with a stability criterion based on a Mott picture of a complex as a bound state in a conducting medium.
