Synthesis
- Heating stoichiometric amounts of pure substances at 2450 °C:
::{{chem2|Ce + S -> CeS}}
- Reduction reaction of dicerium trisulfide and cerium hydride:{{cite journal |last1=Gibbard |first1=Kevin B. |last2=Allahar |first2=Kerry N. |last3=Kolman |first3=David |last4=Butt |first4=Darryl P. |title=Kinetics of thermal synthesis of cerium sulfides |journal=Journal of Nuclear Materials |date=September 2008 |volume=378 |issue=3 |pages=291–298 |doi=10.1016/j.jnucmat.2008.05.013 |bibcode=2008JNuM..378..291G |access-date=4 April 2023|url=https://www.sciencedirect.com/science/article/abs/pii/S0022311508003565|url-access=subscription }}
