Interactions of cadmium fluoride with other metal fluorides are studied. Two compound formation areas can be distinguished in the cation cumulative moment versus electronegativity diagram. Cadmium fluoride is an amphoteric compound in terms of the Lewis theory of acids and bases. Solid solutions (ss) with the fluorite, tysonite (in particular, berthollide phases in CdF 2 –RF 3 , R = Tb–Tm, Y, systems), and α-YF 3 structures are formed in cadmium fluoride systems with rare-earth fluorides. It might be expected that cadmium fluoride would form compounds with francium fluoride, radium fluoride, fluorides of tervalent (Al, Fe, and Ni), tetravalent (Hf, Si, Ge, Re, and Ir) and pentavalent (Ta, Mo, and V) elements, and with uranium hexafluoride.
