Be-Sn (Beryllium-Tin) H. Okamoto and L.E. Tanner The assessed phase diagram for the Be-Sn system is based primarily on the work of [52Ell] and on the present thermodynamic calculation. There is a very wide liquid miscibility gap [37Gue, 50Kau, 52Ell]. No intermediate phases were found in this system [37Gue]. According to lattice parameter measurements on a 0.84 at.% Sn alloy quenched from 1000 C, there appeared to be no solubility of (aBe) [52Ell]. [52Ell] and [74Kob] determined the solubility of Be in liquid Sn by chemical analysis of liquid Sn saturated with Be. [74Kob] also estimated the solubility from the emf values. [52Ell] suggested that the L1 = L2 + (bBe) monotectic temperature is nearly the same as the melting point of Be because of the scatter in the observed arrest temperature. 37Gue: W. Guertler and M.
