摘要

The phase diagrams of trivalent lanthanide-alkali metal halide systems range from simple eutectic systems to systems with one (several) congruently or incongruently 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.
