The Ag-AuS System

  title={The Ag-AuS System},
  author={•IARK D. BARTON},
  • Published 2005
Determination of phase relations in the Ag-Au-S system between 100 ø and 850øC by silica tube, differential thermal analysis, and high-temperature X-ray experiments reveals that the condensed system consists of three basic parts: the Ag-Au complete solid solution, the Ag•.S-Au•S partial solid solution, and sulfur. At low temperatures, two ordered silver-gold sulfides exist, AgsAuS2 and AgAuS; they invert at 185 ø and 310øC, respectively, to a simple, cubic solid solution. Above 310øC a complete… CONTINUE READING
