K-Mg (Potassium-Magnesium) A.D. Pelton The assessed phase diagram for the K-Mg system is based on review of the work of [08Smi], [67Kle], and [73Lan]. The boundaries in the present diagram were calculated from an expression for the activity coefficient of Mg relative to the pure liquid standard state. The K-Mg system exhibits immiscibility in the liquid phase, with negligible solubility of K in liquid Mg and around 1 at.% solubility of Mg in liquid K. Solubility in the solids is negligibly small. No intermetallic phases have been detected by X-ray diffraction [67Kle]. 08Smi: D.P. Smith, Z. Anorg. Chem., 56, 113-114 (1908) in German. 67Kle: W. Klemm and D. Kunze, Proc. Int. Symp. on Alkali Metals, London Chem. Soc., Spec. Pub. No. 22, 3-22 (1967). 73Lan: M.F. Lantratov, Zh. Prikl. Khim. (Leningrad), 46, 1982-1986 (1973) in Russian. Published in Phase Diagrams of Binary Magnesium Alloys, 1988, and in Bull. Alloy Phase Diagrams, 6(1), Feb 1985. Complete evaluation contains 2 figures, 1 table, and 4 references. 1
