Can. J. Chem. 54, 1052 (1976.A re-examination of the LI-In system, based on thermal and X-ray diffraction analysis of 42 alloys, shows it to be more complex than originally reported. This complexity is more consistent with the analogous Li-TI and Li-Ga systems. The solid solubility of Li in In is about 1.5 atyo Li, while that of In in Li appears to be very low. The homogeneous Li-In phase extends from about 46 at% to between 55 and 63 at% Li, depending on the temperature. Of the 11 new phases, 5 with the nominal compositions Li7lQ, LizIn, LisIn3, Li31n, and Li4ln(X) are stable at room temperature, while LiSIn2, LiT31n2,(')), LillIQ, Li41n(x), Li6In and Li121n occur at higher temperatures.W.

There is only one previous study alloy. The X-ray powder sample preparations were carby Grube and Wolf (1) in 1935, which showed ried out in a small 'dry box', which could be Hushed more one equiatoniic compound. This was carried effectively. The argon supply for the dry boxes and for the cooling curve apparatus was passed through: (a) Out using 0'6 g with a very limited (2) and YatsenkO (3)7 respec-of the cooling curve apparatus without any exposure of tively, a ConspiC~ous difference without any the charge to air. The cooling and heating curves were apparent reason. Grahaiii and Raynor (4) briefly present the results of lattice parameter measurements, and report a solid solubility of up to 14% lithiuni in indiuni. The equiatoniic phase LiIn was found by Zintl and Brauer (5) in 1933 to have the NaTl type structure; other work on the LiIn phase has been reported (6-8, 12, 13).

A constitutional diagram for magnesium-indium alloys containing between 23.2 and 100 atomic % indium has been established using differential thermal analysis, electrical resistivity, and metallographic methods.An intermediate solid solution, B, with a wide range of homogeneity, is formed peritectically from the liquid and a, the magnesium primary solid solution. It extends between 23 atomic % indium at 485.3 'C and 86 atomic % indium at 160.2 "C, where it is in equilibrium with y, the indium primary solid solution. Magnesium has a limited solid solubility in indium of about 6 atomic %.For alloys containing up to 50 atomic % indium, the derived constitutional diagram is in good agreement with that of a previous investigation (2). Two exceptions are noted: first, there is no evidence of a long period superlattice, J3"' of the CuAu I1 type, and second, a reaction is observed involving a transition between the two ordered phases J3' and S". For the indium-rich alloys no intermediate or ordered phase formation is observed.The results have been discussed in terms of the cxisting phase diagrams.
