Abstract
This invention relates to the manufacture of Chevrel compounds by sintering a mixture of metal sulfides, metallic molybdenum and molybdenum sulfides under reduced pressure or in a stream of an inert gas containing a reductive gas, and by sintering a mixture of metal sulfides and molybdenum sulfides in a stream of an inert gas containing a reductive gas. This process does not meet any complicated procedure as in prior art and enables one to use a reaction container a desired number of times and to prepare Chevrel compounds inexpensively in large amounts.
