Abstract
The phase diagram of the barium sulfide-copper(I) sulfide system was investigated above 873 K (600 °C) using a custom-built differential thermal analysis (DTA) apparatus. The melting point of barium sulfide was determined utilizing a floating zone furnace. Four new compounds, Ba[subscript 2]Cu[subscript 14]S[subscript 9], Ba[subscript 2]Cu[subscript 2]S[subscript 3], Ba[subscript 5]Cu[subscript 4]S[subscript 7], and Ba[subscript 9]Cu[subscript 2]S[subscript 10], were identified through quench experiments analyzed with wavelength dispersive X-ray spectroscopy (WDS) and energy dispersive X-ray analysis (EDS). A miscibility gap was observed between 72 and 92 mol pct BaS using both DTA experiments and in situ melts observation in a floating zone furnace. A monotectic was observed at 94.5 mol pct BaS and 1288 K (1015 °C).
