Dy-S (Dysprosium-Sulfur) Editor The Dy-S phase diagram is redrawn primarily from [Moffatt] and is based on [ 80Vas] for the 50 to 60 at.% S range and with the assumption that there is no intermediate phase between (Dy) and DyS.The three polymorphic forms of Dy2S3 have been added based on [57Fla] and [60Pic]. The polymorphic transformation temperatures may need further confirmation, because the melting point of Dy2S3 was reported at a substantially low temperature (1490 C) by [60Pic], in comparison with [80Vas]. The DyS2 phase was also added to the diagram based on [59Fla]. The crystal structure data for DyS and Dy5S7 are from [57Fla] and [ 64Ado], respectively. The crystal structure data for polymorphic Dy2S3 are from [Pearson3].--H.O. 57Fla: J. Flahaut, M. Guittard, J. Loriers, and M. Patrie, Compt. Rend., 245, 2291-2293 (1957) in French. 59Fla: J.
