Preparation process for binary sulphur compounds.

摘要

Process for the synthesis of binary sulphur compounds, such as rare-earth and transition metal sulphur compounds. …This process consists in reacting a rare-earth compound, for example oxide or carbonate, or a transition metal oxide with a sulphur carbon compound such as CS2, in a closed vessel at a pressure of between 1 x 10<5> Pa and 150 x 10<5> Pa. …The products obtained are either rare-earth higher sulphides or rare-earth sesquisulphides.
