Cerium phosphide is an inorganic compound with the chemical formula CeP. It is one of the phosphides of cerium. It can be obtained by reacting cerium dioxide and phosphine at 1300 °C in the presence of hydrogen,^[2] or by reacting sodium phosphide and cerium chloride at 700~800 °C.^[1] It will be oxidized to monoclinic CePO₄ in air above 900 °C.^[2] It reacts with iodine in a quartz ampoule to obtain CeSiP₃.^[3]
