Physical DescriptionCerium is a gray colored, ductile solid. This form of cerium is slabs, ingots or rods. When heated to high temperatures it will burn readily and may be difficult to extinguish. It is used to make signaling devices.Cerium, turnings or gritty powder appears as a gray metallic solid. Specific gravity 6.78. Turnings or gritty powder. Contact may burn skin, eyes or mucous membranes. May be toxic by ingestion, inhalation or skin absorption. Used to make other chemicals.Large CrystalsOther SolidGray solid[CAMEO] Ceric salts: yellow or red-orangeCerous salts: usually white[Reference #1] Ductile and highly reactiveReadily oxidizes[Hawley]

Reactivity AlertsStrong Reducing Agent
Reactivity ProfileCERIUM is a strong reducing agent. Resembles aluminum in its chemical properties. [Lewis]. Reactivity is enhanced by a state of high physical subdivision, as in TURNINGS OR GRITTY POWDER. Attacked by dilute and concentrated mineral acids and alkalis with the generation of flammable gases. Readily oxidized by moist air at room temperature. Reacts with zinc with explosively violence. Gives very exothermic reactions with antimony or bismuth. Reacts violently with phosphorus at 400-500 °C [Mellor 8, Supp. 3:347 1971].CERIUM is a strong reducing agent. Resembles aluminum in its chemical properties. [Lewis].
