Cerium - Ce

Cerium is a malleable, soft, ductile, iron-grey metal, a little harder than lead. it's very reactive: it tarnishes readily within the air, it oxidizes slowly in cold water and rapidly in predicament. It dissolves in acids. It will burn if heated or scratched with a knife.

Applications of Cerium

The metal is employed as a core for the carbon electrodes of arc lamps, for incandescent mantles for gaslighting. Cerium is employed in aluminum and iron alloys, in chrome steel as a precipitation hardening agent, to form permanent magnets. Cerium oxide is a component of the catalyst of catalytic converters wont to pack up exhaust vehicles, it also catalyzes the reduction of nitrogen oxides (NOx) to nitrogen gas. All new cars are now equipped with a catalytic converter which consists of a ceramic or metal substrate, a coating of aluminum and cerium oxides, and a layer of finely dispersed metal like platinum or rhodium, which is the active surface.

Other uses of cerium are in low-energy light bulbs, flat-screen televisions, and magnetic-optic compact discs, in chromium plating. the utilization of cerium remains growing, thanks to the very fact that it's suited to supply catalyzers and to shine glass.
