Abstract
Finely divided, high surface area, small crystallite (0.1 micron or less) di- and poly-transition metal chalcogenides are prepared by mixing in the absence of an aqueous solvent a transition metal salt with a source of chalcogen yielding a precipitate. The salt and the chalcogen source can be mixed either neat or in the presence of a nonaqueous solvent. The precipitate which results before removal of the anion salt is a finely divided product.
