A New High-Pressure Form of Sulfur Derived from the Decomposition of S4N4.


A new phase of sulfur is formed from S(4)N(4) held at pressure-temperature conditions in the vicinity of the boundary representing the decomposition of S(4)N(4) to fibrous sulfur, S(x). The new phase is gray-black, is persistently metastable at room conditions, and is insoluble in carbon disulfide. The phase is apparently formed from a stage of… (More)
