Abstract

Binary rare earth/sulfur or transition metal/sulfur compounds, e.g., the higher sulfides or sesquisulfides of the rare earths, are prepared by confinedly reacting either a rare earth compound, e.g., an oxide, carbonate or hydroxide, or a transition metal oxide, with a carbon compound of sulfur in gaseous state, e.g., CS.sub.2, within a sealed enclosure.
