Lutetium molten, density

Lundin (1966) tried to include alloys of the lanthanum-lutetium system in his study of the formation of the samarium-type structure in intra rare earth alloys. The wide differences in the melting points (La 918°C Lu 1663°C) and densities (La 6.146 g/cm Lu 9.841 g/cm ) allowed the lutetium to settle to the bottom of molten lanthanum during the alloying process. Alloys were inverted and remelted several times to improve the homogeneity. Lundin reported (1) lanthanum-lutetium alloys formed a complex microstructure that had a different appearance than that of the samarium-type structure formed in the other alloy systems between a light and a heavy lanthanide or yttrium metal and (2) X-ray analysis failed to confirm the...
