PHYSICOCHEMICAL STUDY OF PHASE-DIAGRAMS OF NDBR3-MBR SYSTEMS (M=K, RB)

Fusion diagrams of the NdBr3-KBr and NdBr3-RbBr systems were studied. The formation of 1:2 and 3:1 compounds was found. Comparison of data obtained and known earlier showed that the character of the compounds formed depends on the ionic radius of the alkali metal (K, Rb, Cs).
