Sodium–strontium phase diagram: redetermination of the solubility of strontium in liquid sodium
Abstract
The sodium-strontium phase diagram has been redetermined up to 37.9 mol % Sr (439 °C). Considerable differences from existing data have been found; the solubility of Sr is less than previously reported and the eutectic point located at 0.65 mol % Sr and 94.80 °C. The solubility is compared with those of the other Group 2A metals in sodium: whereas Be. Mg. and Ca are virtually insoluble, Sr is quite soluble but not to the extent shown by Ba.
