ABSTRACT
As the density of elemental sulfur was determined on slowly cooling from 508 K, it was unexpected for the metastable molten state to be maintained to temperatures as low as 334 K, thus expanding by about 20K the T-range within which experimental data become available. In the 334 430K range, the density . of the metastable molecular melt was fitted to . (g cm-3) = 2.18835 0.00098187T (K), subsequently leading to volumic expansion coefficients aV(T) =-(1/.(T))(../.T)P of 5.28*10-4 K-1 at 334K and 5.56*10-4 K-1 at 430 K.
