Abstract
Molybdenum disulfide powders include substantially spherically-shaped particles of molybdenum disulfide that are formed from agglomerations of generally flake-shaped sub-particles. The molybdenum disulfide powders are flowable and exhibit uniform densities. Methods for producing a molybdenum disulfide powder may include the steps of: Providing a supply of molybdenum disulfide precursor material; providing a supply of a liquid; providing a supply of a binder; combining the molybdenum disulfide precursor material with the liquid and the binder to form a slurry; feeding the slurry into a stream of hot gas; and recovering the molybdenum disulfide powder, the molybdenum disulfide powder including substantially spherically-shaped particles of molybdenum disulfide formed from agglomerations of generally flake-shaped sub-particles.
