Abstract: The regularities of melting behavior for nine kinds of stoichiometries including 311compounds were discussed by pattern recognition method with bond parameters as features. The compounds of the nine kinds of stoichiometries were MeMe′X2 , MeMe′X3 , Me2 Me′X4 , MeMe′X4 , MeMe′2 X5 , MeMe′X5 , Me2 Me′X6 , Me3 MeX6 and MeMe′2 X7 respectively (Me, Me′denote metallic elements, X denotes halogen). It has been found that the congruent or incongruent melting of intermediate compounds in molten salt systems distribute in different regions. In addition, four general regularities for melting behavior of halides were summarized on the basis of the nine semi-empirical models obtained from the known phase diagrams.
