Uses · 3건

Used in metal alloys, in polishing agents, and in glass; [Ullmann] Sources: most abundant of the rare earth metals, it is obtained mainly from monazite, and bastnasite mineral deposits. Large deposits are found in India, Brazil, and the United States. Uses: to manufacture flints for cigarette lighters (misch metal); to make incandescent gas mantles, self-cleaning ovens, carbon arc lighting, and glass; as an analytical reagent (Cerium sulfate); to polish glass (Cerium oxide); and as a catalyst in petroleum refining; [Reference #1]

Reactivity Profile · 2건

CERIUM 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].
