Phase Relations in the Fe-As-S System.
The phase relations in the Fe-As-S system at 600°0, studied in rigid silica glass tubes where a vapor phase is always present, are as follows: a liquid field extends along the S-As join from 100 to 22.8 +/- 0.2 weight per cent sulfur. An extensive pyrite-liquid-vapor field and a narrower pyrrhotite-...

| Summary: | The phase relations in the Fe-As-S system at 600°0, studied in rigid silica glass tubes where a vapor phase is always present, are as follows: a liquid field extends along the S-As join from 100 to 22.8 +/- 0.2 weight per cent sulfur. An extensive pyrite-liquid-vapor field and a narrower pyrrhotite-liquid-vapor field are separated by the four-phase region pyrite-pyrrhotite-liquid-vapor in which the composition of the liquid is, in weight per cent, approximately As = 62.5, S = 37.5, and Fe = 0.11.
