Product Description

 

Description

Lanthanum Metal is a cast silver-gray metal that is easily oxidized in the air. Lanthanum metal is used as an important additive or alloying element for the production of special steel, non-ferrous metal alloys, and hydrogen storage materials, and it can also be used as a reducing agent for the production of other metals.

Air and Water Reactions: 

Light sensitive Moisture sensitive Air sensitive

Reactive Group: 

Metals, Elemental and Powder, Active

Reactivity Alerts: 

Strong Reducing Agent

Reactivity Profile: 

YTTRIUM in bulk is stable in air due to the formation of oxide films. Powder or dust is light-sensitive and air-sensitive and flammable in the air and (Hazardous Chemicals Desk Reference, p. 861 (1987)). Reacts with water to form gaseous hydrogen (H2). Reacts with strong oxidizing agents, strong acids, strong bases, and halogens. The products of these reactions are irritating and toxic.

Flammable Limits: 

Noncombustible Solid in bulk form.
