Abstract

The diarsenides and sulpharsenides of Fe, Co and Ni have been investigated at 500 and 650 degrees C, with a focus on phase relations in the As-rich regions of the (Fe,Co,Ni)(As,S) (sub 2) prism. Alloclasite, arsenopyrite, cobaltite or gersdorffite are in equilibrium with diarsenide (sub ss) , loellingite, krutovite or safflorite. Coexisting skutterudite and pyrrhotite occur in equilibria with all these phases except krutovite. At 650 degrees C, most phases show extensive soild solution; there are complete solid solutions between safflorite, alloclasite, skutteruite and their respective (Fe (sub 0.5) Ni (sub 0.5) ) analogues. There is also a complete solid solution between cobaltite and gersdorffite. At 500 degrees C, these solid solutions are more restricted but still show a large variation in As-S contents.
