Cerium sulfides were prepared by high‐energy milling of cerium and sulfur. The reaction kinetics were observed by monitoring temperature and pressure in situ . For the first time, it is demonstrated that cerium monosulfide, which has historically been produced only at very high temperatures using both toxic and flammable gases, can be produced from a stoichiometric mixture of the elemental powders at near room temperature. It is shown that the monosulfide is produced through a mechanochemically induced self‐propagating reaction of intermediate compounds.
