Physical Description
Cerium 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.

Verwendung und Herstellung
Uses
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]
