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.
Claims17
A process for the preparation of a binary rare earth/sulfur or transition metal/sulfur compound, comprising placing either a rare earth compound or a transition metal oxide with a carbon compound of sulfur in a reaction enclosure, sealing said enclosure and confinedly reacting either said rare earth compound or said transition metal oxide with said carbon compound of sulfur in the gaseous state, in said sealed enclosure without removal of reaction products.
