Li-Sr (Lithium-Strontium) C.W. Bale and A.D. Pelton Although the phase diagram for the Li-Sr system is not well known, particularly on the Sr side, up to five intermetallic phases have been reported at 1 atm pressure. Li23Sr6 and LiSr3 are well established, but the existence of the other three intermetallic compounds is in doubt. The Li-Sr system exhibits very limited solid solubility at both ends of the diagram. The assessed phase diagram is based primarily on the work of [ 60Kan], [60Wan], [62Wan1], [62Wan2], with dashed lines representing important modifications made by the present evaluators to the diagram of [62Wan2]. The dashed liquidus was calculated from thermodynamic principles using select experimental data from [62Wan1] and [62Wan2] and assuming negligible solid solubility of Li in (aSr) and (gSr). 60Kan: F.A.
