K-Ta (Potassium-Tantalum) S.P. Garg, M. Venkatraman, and N. Krishnamurthy A comprehensive investigation of the binary Ta-K system has not been reported. The Ta-K phase diagram presented here is speculative. An assessment of the solubility of transition metals including Ta in liquid K was made by [66Gin] and [67Ant]. The invariant temperatures for the three-phase equilibria (Ta) + ( K) + (liquid K) and (Ta) + (liquid K) + (K vapor) shown in the assessed diagram are based on the phase transformation temperatures of pure K. No evidence for the existence of intermetallic phases in this system has been reported. 66Gin: W.S. Ginell and R.J. Teitel, USAEC, Conf. 650411, 44 (1966). 67Ant: D.F. Anthrop, USAEC, UCRL-50315, 91 (1967). Published in J. Alloy Phase Diagrams, 6(1), 1990. Complete evaluation contains 2 figures, 1 table, and 7 references. 1
