The equilibrium solubility of the refractory alloy Cb-1 Zr in liquid sodium in the temperature range of 800 to 1380 C was determined under static, isothermal conditions. The standard comparator method of activation analysis was used to determine the columbium and zirconium content of the equilibrated sodium samples. The solubility ranges were estimated to be 0.25 to 250 ppm and 0.08 to 4 ppm by weight for columbium and zirconium, respectively.
