Li-Nb (Lithium-Niobium) J.F. Smith and K.J. Lee Only limited data are available concerning the Li-Nb phase diagram. Most work concerns determination of the solubility of solid Nb in liquid Li, and wide scatter of results and contamination preclude quantitative analysis. Empiricism [69Sav] and theory [80Deb, 83Nie], however, indicate extensive immiscibility in both the liquid and solid states. The assessed phase diagram was based on the data of [Hultgren,E] and [83Cha] and represents the Li-Nb system at a constant pressure of 1 atm. 69Sav: E.M. Savitskii and Yu.V. Efimov, Planseeberichte fЃr Pulvermetallurgie, 17, 103-109 (1969) in German. 80Deb: F.R. deBoer, R. Boom, and A.R. Miedema, Physica B, 101, 294-319 (1980). 83Cha: M.W. Chase, Bull. Alloy Phase Diagrams, 4, 124 (1983). 83Nie: A.K. Niessen, F.R. deBoer, R. Boom, P.F. de Chatel, W.C.M. Mattens, and A.R. Miedema, Calphad, 7, 51-70 (1983). Published in Bull.
