Cr-Rb (Chromium-Rubidium) M. Venkatraman and J.P. Neumann The assessed Cr-Rb diagram is assumed to be similar to the Cr-Li and Cr-Na diagrams, which exhibit very small solubility of Cr in the liquid and, presumably, also in the solid state. No information is available concerning the nature of the three-phase equilibria involving (Cr), (Rb), and liquid Rb at ~39 C (~313 K), or between (Cr), liquid Rb, and Rb vapor at ~688 C (~961 K). The solubility of Cr in liquid Rb was obtained by [62You], who equilibrated liquid Rb with Haynes 25 alloy crucibles (nominal composition in wt.%: Co-20Cr- 15W-10Ni-3Fe-1.5Mn-1Si-0.1C). The solubility of Cr was on the order of 10-3 at. % between 700 and 900 C (1000 and 1200 K), which is on the same order as the solubility of Cr in liquid Li, Na, or Cs. 62You: P.F. Young and R.W.
