Abstract:
The phase diagrams of trivalent lanthanide–alkali metal halide systems range from simple eutectic systems to systems with one (several) congruently or incongruenly melting compounds. Using both literature information and our extensive experimental results, the LnX3-MX binary mixtures phase diagrams were screened in terms of the IPM+/IPLn3+ ratio (IPi= zi/ri ; zi: ionic charge; ri: ionic radius; Ln: lanthanide, X: halide and M: alkali metal). A similar approach was conducted on the divalent LnX2-MX lanthanide-alkali halides phase diagrams ranging from simple eutectic to one or more congruently melting compounds. Lanthanides being widely used as simulants of actinides, this classification can constitute a useful predictive tool for those still unexplored systems.
