Фазовая диаграмма системы K-Li

K-Li (Potassium-Lithium) C.W. Bale K-Li is a simple system with three phases: (1) pure solid K; (2) pure solid Li; and (3) the liquid, which is miscible only at much higher temperatures (>1500 C) where the vapor becomes appreciable. According to the thermal analyses of [ 39Boh], Li and K do not alloy, and there is no evidence for either intermediate compound formation or solid solutions. The assessed diagram was obtained by thermodynamic modeling of the solubility data of [70Dot] and [ 74Smi]. The transition temperatures were taken from [Melt]. 39Boh: B. Bohm and W. Klemm, Z. Anorg. Allg. Chem., 243, 69 (1939). 70Dot: L.E. Dotson and R.B. Hand, GESP-603-R-71-NSP-2 prepared for NASA under contract NAS 3-6474 (1970). 74Smi: F.J. Smith, J. Less-Common Met., 147 (1974). Published in Bull. Alloy Phase Diagrams, 10(3), Jun 1989. Complete evaluation contains 2 figures, 2 tables, and 5 references. 1
