Popis: Ternary NaF–LiF–LnF3 (Ln = La, Nd) systems of eutectic compositions were studied by means of X-ray diffraction method in the solid and liquid states. It was found that the crystalline phases LiF, NaF and NaLnF4 coexist in the solid state up to the melting temperatures. Above the melting point, a decrease in the nearest interatomic distances with a pronounced minimum has been observed, which correlates with the extreme behaviour of the temperature-dependent structure-sensitive physical properties of the investigated alloys.
