Abstract

Equilibrium open-circuit cell voltage data from a sodium/{beta}{double_prime}-alumina/phosphorus-sulfur cell utilizing P/S ratios of 0, 0.143, and 0.332 and a sodium atom fraction ranging from 0 to 0.4 were interpreted to construct ternary phase diagrams of the Na-P-S ternary system at 350 and 400 C.
